what would you do ?

so me and my boyfriend have been together for about 4 months and we will go over to my friends house, she has a bf and so my bf and her bf could hang out while we hung out. but anyways there was like 75 cents on the ground outside her house in the gravel, my bf picks it up and puts it in his pocket... then the other day we went to go pick my son up from her and he came inside with me to get my son and he was talking to me but a little loud i told him to be quiet because the baby (3 mnths old) and the bf was sleeping and my friends bf woke up, well we left like 5 minutes after. and then maybe an hour or so later i get atext from her saying that her bf and his brother (his brother lives with them also) agreed that they do not want him over at their house anymore, because it was disrepectful to pick up the change on the ground and keep it.... (when the change was on the ground for at least a couple days because we go over there a lot) and they didnt like how he came in talking all loud waking the bf up. so all i said was ok. and i havent talked to my bf about it because i dont want him to get mad at ME or upset. i am not planning on going over anymore because if hes not invited over im not going over.. but im just not sure how to tell him about it. he has depression so he will think badly of himself when he really shouldnt have too. i mean yeah he couldve been more quiet but i dont really see anything wrong with picking up the chnage and keeping it.... if my friends wanted the change then they shouldve picked it up or not even have it on theground where ANY one could get it. so my question is how would you let your bf know that your friends dont want him over anymore because of those 2 silly things.... ?
