Losing a friend?

Well, if your friend was really your friend, theyd still be your friend no matter what. If not, then theyre probably not a true friend to begin with. Learned from experience.

I agree with Para, not all friends' parents will like you. Some people just have an instant dislike to people without even getting to know them, and unfortunately there's nothing we can do about these shallow people apart from ignore them.
If you're sure your friend will stick によって you, ask if she's willing to allow あなた to talk to her mother and sort this out once and for all.
If she's willing, call round and ask politely to speak to her mother, sit down and explain how you're feeling and why and ask whether there is something あなた have done that has offended または upset her in any way. Just say that if there is, あなた would like to apologise for it, even though あなた didn't mean to as the bitterness between the two of あなた is hurting your relationship with your friend and あなた are worried about it. Tell her あなた value her daughters friendship with あなた and would like it to continue for as long as possible.

if she doesn't have what あなた think is a valid reason for disliking you, または doesn't accept your apology, then all あなた have to say is fine, i was the bigger person, i came to apologise and あなた didn't accept, but i'd still like to be フレンズ with your daughter and あなた can not stop me from talking to her または helping her out when she needs me to. The calmly walk away, saying to your friend, "i'll see あなた at school". Don't forget to thank your friend for being willing about this too, just in case your friend's mother picks up on the little things like that.
Try to keep あなた voice calm and at a low level, even if she starts to yell don't yell back. If she won't let あなた get a word in edgeways while she's yelling her head off at あなた あなた have two choices - 1. either get up calmly say i'm sorry i upset あなた i'll leave now but i'd still like to continue this when you've calmed down, and then walk away. または 2- sit the yelling out until she pauses for breath and continue with what あなた were saying.
But whether she likes あなた after, または hates あなた もっと見る または even whether she hated あなた in the first place and just wants her daughter to stay away from you, the choice is not hers.

loosing フレンズ are the worst i would cry if i ロスト mine. I say her mom a letter apologizing for anything that may have caused her mom to diss like u. and tell ur friend to give it to her. GOOD LUCK

Ok thats not an easy problem to solve. Personnaly I think I would go and see the parent of your friend and ask what she feels あなた have done to deserve this. Take your mum with あなた for moral support. I would think in her eyes あなた must of done something terrible. Find out and if あなた can explain why what ever it was happened and promise her that あなた have または will try your best to change and that having your friend her child is important and may help あなた in the end. Oh yes and from this adult to あなた if ever someone says it gets better once あなた are an adult don't believe them my mother is still on my case and I am 36 mind あなた I do still live at ホーム but it is highly annoying. Anyway good luck.
