One and a half years. Especially, since July 2014.

Did you have another computer before this one? 

I had one from the end of 2009 till the end of 2012. It was off because of charger issues. Didn't have a computer throughout 2013, because I was working part-time to pay money to fix the charger or to buy a new one, so I sometimes went to my friend's computer to play and browse at that time, and in 2014, I had the same computer with a fixed charger, but it only lasted 6 months, before crashing due to me downloading a torrent file :(

Then, I use the computer I type right now.

They are poor, plus they had to pay much money for my sister's computer's new hard disk, because she knocked her computer from her anger.

You count the days, right?

That's really ... weird.

Knocking a computer because of anger sounds like a pretty bad reason to have them buy her a new one. Is she angry in general or was this a one-time situation?
