:'(what do you guys think could be the reason for this person to do so.as long as I remember I have not hurt this person nor could I even think of it.how could I make up to this person because he was a great influence ofcourse positive.
if in my view you may accidentally mock or hurt your friend. so your friends feel hurt and leave you.
try to speak well and ask if you have any wrong. if he still does not answer try joking with a little silly style or something funny so he can be a little entertained.
