If your sister is younger, it might be for attention. If she's older, it might be to show that she's the dominant sibling.
Just because they are your friends does not mean they have to be each others friends.
From the standpoint of etiquette your sister should take precedence. After all, your sister is your sister for life. Best friends sometimes fall out of favor (or, at least, diminsh in contact - sometimes - over the years).
cause she is bored and wants your friend to think she is awsome
get some of your friends over and go to your sisterroom and move all her furniture,clothes,and jewleries anything that is in her room outside your back yard or outside your house(only do this when your sister and parents arent home)then go somewhere beside your home then when your parents get home and ask you y ur sister stuff is outside,say: "I don't know I was playing at my friends house.
I know how you feel. That same thing happened to me. You should try to find out why they hate each other. Then you should ask each of them what they hate about the other. Then think about which one could be friendlier than the other, or which one would help you if you needed them, and which one would be nice to you.
All of your friends are bad people if they hate you, unless if you're the bad egg. Did you do something to cause this? Do they think you did something? If you did, apologize for it. If you didn't do anything, tell them so and get on with your life. Whether they'll get over it or not, you shouldn't try too hard to make them like you; try to make other friends.
Your sister just wants to be part of things and feels grown up enough to do so. Talk to your parents at that is their responsibility to control your sister when you want some privacy with friends, but, at least let your sister spend 20 minutes with you and your girlfriends and then tell her she has to go (have your parents back you up on this.)
they hate being tickled over and over again and they also hate being ignored.
Heterosexual relationships involving the siblings of friends increase the chances that the reactions will be either very good or very bad. On one hand, there are brothers-in-law who are best friends, and on the other there can be bad blood between former friends over how the sister is treated.
Okay Miley Cyrus Dosen't Hate Selena Gomez And Demi Lovato That Much Just They Had A Fight In The Past , And Selena And Miley Fighting Over Nick Jonas But Now Nick Jonas Wanna Be Lonley , But You Can Say They Are Normal Friends .
Friends may only come to you when they need you when they prioritize their own needs over the friendship, seeking help or support only when it benefits them.
People in England hate Arabs because Arabs and Muslims have been taking over areas of their country.
