so to preface, earlier this week it was birthday (17 woohoo!). yesterday i went into town after school to check out some video games. eb games (yes we still have it in nz) have a half price for pre-owned games sale going on, so i pick up mass effect for $8 ($5.44 usd). i played the first level last night, loved it, and went back into town today to grab mass effect 2 and 3 while they where on sale.

so, the fu. i went with my mate (let's call him bob) and he's known for being a bit of an asshole sometimes. while we were browsing the games, i spy a [metal-case limited addition copy of bioshock](http://gameoffer.com/435/bioshock-xbox-360.jpg) on my platform (xbox 360). the thing looks pretty as fuck, so i go over to check it out. i look at the price tag, and lo and behold, they are selling that thing for $8. that is, again, $5.44 for you muricans. i can't believe it, and immediately announce that i'm gonna buy it. i've played bioshock infinite (booker, catch!), and have always wanted to play the others, so this was great for me. bob has played bioshock on pc, and really likes the look of the game as well, he keeps going on about how he want's the game instead, so he can get the achievements and such. he asks to have a quick look at it, and, like a good friend, i give it to him. he immediately says, okay, i'm gonna buy it. 

i get kinda worried, like i know he'll give it back eventually, won't he? he's not *that* much of an asshole. he starts lining up with a eb games gift card he had, conveniently with $8.40 on it. i keep saying "alright dude, that's not funny anymore, give it back," but he continues to refuse saying "don't worry about it" and "it'll be fine bro". i start saying that if he buys that game, i'm gonna be so angry at him i'm probably gonna stop talking to him for a while. it's happened before where he's been an ass and i've ignored him for a week or two.

so anyway, i start trying to snatch it off him, but he's a lot bigger than me and i don't manage to get it off him. he eventually gets to the front of the line and starts buying the game. i am *livid* at the moment. fully prepared to buy my mass effect games once he's done, and walk out of the store without him. he pays, while i'm behind him, not believing what he's doing. he finishes up paying, turns around, holds the game out to me, and says "happy birthday".

i'm so done. i didn't know emotions could possibly change that quickly. i quickly try to say "thank you" and "sorry" at the same time, since i'm now at the front of the line, and grab the metal-case. i quickly buy my games, then turn around to see him smiling at me. 

cue profuse apologies and immense gratitude. i was, and still am, so sorry that i didn't initially trust him. when he said "don't worry about it" and "it'll be fine bro," i should have listened, and trusted him.

but honestly, i would rather have bought the game for myself, since now i have to buy him a gift of equal or greater value for his birthday. at least it's only $8.

bob, thanks man, and sorry.

TIFU by not trusting my friend.
