Extroverts might have a hard time understanding this. Since most likely, they enjoy their time more with people and talking and interacting with one another. However, introverts will agree on what I have to say.
Being alone means a lot of things. It comes with the idea of having your hobby, making yourself comfortable and happy in a way that only you can understand, and do things on your own. Most of the time, I most likely find myself being happy on my own rather than going out with other people, even with my friends. Although I kind of missed talking with them and us, going to places, at the same time, I enjoy the time with myself.
On the other hand, being alone also comes with negative things. Ever since I was a kid, I find myself lacking the ability to interact with people. I keep my mouth shut most of the time to the point where if no one talks to me then I won't talk unless I'm being asked or someone wants to have a conversation with me. Even with a circle of friends, I prefer a small group. I don't know any idea about hanging out with more than 5 people and sometimes I think, some of them might not be true to one another. However, I think it's about maturity, if you can handle mature stuff, in every sense of the word, then having a lot of friends is okay. But I don't think this applies to kids and teenagers most of the time. Kids must interact with other kids, build the friendship and bond that they're looking for, and enjoy things in life. And for a kid to stay in an area that doesn't have more kids to play with is not a good sign. For me, I experienced that but it isn't because I experience terrible things at home, I just prefer to be on my own. And by that, growing up, it's hard to make friends since you didn't practice it when you were a kid. I still have the attitude of not talking to a person unless the person talks to me and that's because of the reason that they might not like me. Having the idea of the person taking the initiative to talk to you, as an introvert, means that they like to chat and has a positive vibe towards you.
I also want to talk about having trust issues. So I most likely judge a person's behavior and way of talking since I got trauma from people who tend to look and talk like they're kind and honest. And by that, I have a hard time believing someone, especially it's the first time we talked.
On the positive side, being alone is having fun, on your own. It gives you a lot of time to think about yourself. To know more about you and what you want to do, in your day-to-day life. Since you don't have to talk to someone most of the time, all you have is yourself. You may not physically talk to yourself but your mind tends to tell you something, maybe about your future or about yourself. It also gives you peace of mind, unless people around you at your house are all talkative then that is another case.
As an introverted person, I will tell you things that you can do to still have that positive attitude, even with being alone.
When going to public places where people are likely to escort you, in any form of way, say "Thank You.". It gives both of you a positive vibe towards one another and you're likely to be considered polite and understanding.
Always be mindful of your surroundings. If they don't care much about your presence then it's a good thing, you're most likely to not be a target if something happens. Also, know the place or area. However, if the otherwise occurs, move to the place that has a lot of people, they won't notice it or in some luck, they will consider you as part of them until strange things disappear.
Never deal with your phones unless you find them the only ones making you laugh. If phones are your go-to place to escape the real world then so be it. It helps you get relaxed and stop or lessen the negative vibes.
Smile or bow as an interaction. As an introverted person, I don't say "Hello" or "Hi" to most people but smile or doing a bow is a good thing. All people are judgmental anyway, but still, make yourself as if people will run to you and remember you in case they're in trouble.
Always be mindful of yourself and the people you love.
Being alone doesn't always being mean being lonely.
Always take care of yourself and be nice to other people, unless they're not nice then do otherwise.
