did she purposely hide it?

[Sarah]

yesterday was my birthday and my sis texts me happy bday. She usually posts on my wall on facebook as well. She didn't this time and when i asked her she says shes not going to. I said y? and she says u really want me to. I go its not that , you do it every year and this year u didn't is something wrong. She says its bc she would've wrote an embarrassing message and asked me if i really wanted ppl to see it. I feel like she was making a excuse. She wrote on my wall but when i checked on her profile it doesn't say she posted on my wall. did she hide it or remove it from her wall. We were always close but then my sis moved with my mom bc of my dad and we stopped talking but were started to chat again. Her friends don't like me. So i was wondering if she is trying to hide the fact she is talking to me. I asked her and she said she didn't remove it.
sorry for the bad spelling and grammar.
ok seriously, just because I used short forms for some words and didn't make sure its edited perfectly doesn't mean i'm retarted ok. Keep your rude comments to yourself.
When you write on someone's wall, on your wall it would say you posted something to that person right? Since iher wall never said she posted anything on my wall, it means she hide it or removed it from her wall. Am i right?
I'm not upset that she didn't want to write on my wall, and im not saying ppl have to say it twice to me, i'm upset because its like she is trying to hide the fact she is talking to me because of her friends. Like she doesn't want to be seen talking to me.
my friends bday is today and i posted happy birthday on there wall but it never showed up on my wall saying i posted on there's. I guess its a facebook thing , oops i overreacted that's embarrassing
