Is it normal to "steal" sisters friend?
I have this friend that is also my sisters friend and my sister hates that i'm friends with her..well she never used to care until now(i've been this persons friend for about four years now) and i don't know why she cares now but she gets upset if me and that friend spends time together and it seems like she gets jealous. she has even tried telling me that i shouldn't be her friend. so is this normal? should I feel guilty? bc i do.
