It's good you didn't say anything rude to your friend Shane. That would really hurt him. Try and do some physical activities when you two hang out. And at lunch ask your other friends if you can throw their "trash" or leftovers for them. As for your friend showing off his weight, tell him that your a bit embarassed by him showing off his body. Just don't show off your body either because that would be very hipocritical. Need any more advice or if Shane does, write to me at Roo5spoons@aol.com
