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 by you, ask if she's willing to allow you 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 you have done that has offended or upset her in any way. Just say that if there is, you would like to apologise for it, even though you didn't mean to as the bitterness between the two of you is hurting your relationship with your friend and you are worried about it. Tell her you value her daughters friendship with you and would like it to continue for as long as possible.

if she doesn't have what you think is a valid reason for disliking you, or doesn't accept your apology, then all you have to say is fine, i was the bigger person, i came to apologise and you didn't accept, but i'd still like to be friends with your daughter and you can not stop me from talking to her or helping her out when she needs me to. The calmly walk away, saying to your friend, "i'll see you 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 you voice calm and at a low level, even if she starts to yell don't yell back. If she won't let you get a word in edgeways while she's yelling her head off at you you have two choices - 1. either get up calmly say i'm sorry i upset you i'll leave now but i'd still like to continue this when you've calmed down, and then walk away. Or 2- sit the yelling out until she pauses for breath and continue with what you were saying.
But whether she likes you after, or hates you more or even whether she hated you in the first place and just wants her daughter to stay away from you, the choice is not hers.

loosing friends are the worst i would cry if i lost 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 you have done to deserve this. Take your mum with you for moral support. I would think in her eyes you must of done something terrible. Find out and if you can explain why what ever it was happened and promise her that you have or will try your best to change and that having your friend her child is important and may help you in the end. Oh yes and from this adult to you if ever someone says it gets better once you are an adult don't believe them my mother is still on my case and I am 36 mind you I do still live at home but it is highly annoying. Anyway good luck.
