does having more bags considered a sin?

(bro walks into my room and stand behind me, suddenly he speaks up)
BRO: OI! what you doing?!
ME: I'm looking at bags.
BRO: ....
(suddenly he
smacks my head)
ME: OUCH!
BRO: You wanna die ah, so many bags le still
want to buy some more?!
ME: Looking through only.. I never say I wanted to
buy. HAHA.
(bro walks aways.)
(HAHAHA. actually I wanted to buy them.
=X)

Anyway, yesterday at work was a chore. I was happily doing the cashier when I didn't even realise the photo frame beside the counter was stolen. OMG!

I CURSE AND SWEAR THE PERSON WHO STOLE THE PHOTO FRAME, HIS/HER HANDS WILL ITCH LIKE NOBODY'S BUSINESS!!!!!!!!!!!!!!!!!! Steal some more.

I'm so so so angry OK!!! Why'd this happen to me when I do cashiering.? I know I very SLOW. but why do this to me?!

Feel like breaking the person's bones! WTH!
