Asking for help

My class consist of 40+ students and I think among all of them, they're still some of them that I've never spoke to. Including this one guy. Actually, I've talk to him once in the 1st semester when we're in the same group but I stopped talking to him after I got scolded by him. I hate him so much that I never talk to him for the next 3 semester and he do the same. Now, in the 4th semester, he suddenly started to talk to me again & I think it's  time for me to forget about what had happened between us. Today, I've asked him something regarding our assignment and surprisingly he helped me. Thanks to him that now I know how to do my assignments. yay.
Oh, silly me. Look at how immature am I.
