to get back at your sister i would probably put something in her bed or get and old book with old blank pages and make it about her and then copy all her secrets in it and once you have photocopy the pages and give them to some people at your sisters school.
Warning: only do it if you want to suffer the things she does if she finds out
if she finds out then your toast
Try to ignore her.
ignore them
no she isnt
it depends on how shes annoying you
Because that's what they like to do.
cos she is
tell her to go do it by your self
I don't have one ,but my friend has a really annoying little sister ,and trust me she is ANNOYING!!!!!!!
She can't hate you... She's your sister and she loves you, but you might be annoying her
Hahahaha I believe all younger siblings can be annoying at some points, but they will always love you.
On your little annoying sister's birthday.
tell her your annoying trust me
Just don't talk to her cause I have a little sister
