Backstory:
A few nights ago I stayed up on my computer until about 2:30. My mom woke up and caught me and freaked the hell out since I'm supposed to be asleep by 11. >:(. I told her I was looking up information about Minecon, but I was really playing TF2. She's extremely strict. Game has a gun in it? CANT PLAY IT. Movie says crap once? OH NO YOU AINT WATCHIN' DAT, SON. If she found out i've been playing TF2, GTA, HL2 etc she'd prob take my computer away for good. Anyway all has been good until tonight she comes in and says she wants my computer password so she can check that I was on the Minecon stuff.
Shat.
I clear my history nightly and I have no clue what I should do. I've gone through my computer and deleted every violent game/shmexy pic on my system (still am going through them) and I fear she'll find something. She isn't exactly the brightest with computers though although I still feel she's invading my privacy. If I say anything about privacy though she'll become extremely suspicious and ask me why I need privacy. That I have no answer for.
I've never swore in front of her, let her see violent games, been caught fapping etc. To her I'm basically a goody-two-shoe except I unwittingly talk back sometimes. I do not know what to do and she wants that password soon.
TL;DR my strict mom wants to snoop on my computer that she has no knowledge of being ridden with GTA/TF2/HL2/research and if I say anything about privacy she'll be even more suspicious. Wat do.
Yes, I am only 12. (13 in a month.) I feel no reason I should be discriminated for my age, this is a game about online legos and I'm just looking for advice on an IRL problem.
