How to conquer your foe or enemy?

This is my first writing on this site as this day only i discovered this tru browsing..i dont know why that title comes first on my mind, but lately i realise it was what happening to our club in tennis recently. So many bad circumstances happen, so it comes to my mind to take actions by giving them advices and some tips on how to beat and conquer your enemies or foes. What happen was the never ending bad conversation tru chats and they keep and keep arguing things no one accept who's fault. So i said to one of them, if you really want to settle him, join him and stop arguing and thats the only way.. So its done. Now they are on peace..
