I have some friends spending dinner at home for 3 weekends now, they're 3 different set of friends. One was my MBA colleagues, another my highschool classmates and the other a mix of friends with no particular description. My niece asked me what group next lol. Told her I have different sets of friends because I got lot of friends. I've met a lot of people as I grow up and living in different places till I settle for good in my home town. Listing them down would take a lot of pages.
