family question? please answer, sorry if it's long?

[movieguy92]

ok, so i have a facebook, and whenever i write on my aunts wall, she won't relply, i even messaged her, and she didn't reply, so if she does reply should i say "well well well, look who decided to write back"or if i go to canada(my family lives there), and she talks to me should i say "oh, so now u decide to talk to me, what made u do that." please tell me what i should do

and please no nasty comments thanks
to madi: yes sometimes she is online, but when i'm not on, it's probably late at night, and she get's them, but she probably deletes them
to numb:i'm 15, so yeah, and i don't have her number
