Well I didn't follow your EXACT advice
Instead I made sure not to make fun of her, or at the very least, not make fun of the things she's sensitive about.
Like how big her nose is, and comparing it to a beak.
She always makes fun of how big my forehead is, and I made sure that if she brought up something like that, I would just walk away.
Which led her to apologizing to me instead.
And we've gotten the message across NOT to make fun of things that bother us to much.
And about the whole "Cutting off the friendship" thing. I ended up saying something to try and prove I have the higher power.
Alot of the time whenever I try and hang out with my other friends, Katherine will literaly tug me away from them, and since my other friends practically hate Katherine, you can see where it can be a problem.
But anyways during sometime today I made it apparent to Katherine that if she were to lose me, the only friends she would have to hang out with are Kelsey and Kyla.
We used to be one big group of friends, but Katherine ended up getting pissed at Kelce (Diffrent from KelSEY) because they didn't hang out that much over summer and immediately cut off the friendship.
She didn't even talk to her when school started, thus seperating the group. I've tried to stay on both sides but ended up getting closer to Katherine than I thought.
BUT I've known Kelce a hella lot longer than I've known Katherine, and Katherine has been known to end a LOT of friendships over stupid reasons...which is why she really only has me Kelsey and Kyla anymore.
