Thanks to you, my sis lost all her stuff. Including her writing portfolio. And does she have backups on her laptop? NO. It may not strike you as important stuff but it was to her. The least thing you could do was apologise when she told you about it. Even if you didn't know that she lost her portfolio (along with a gazillion other stuff), it is a common courtesy that when you spoil someone's item, you a-p-o-l-o-g-i-s-e.

I was trying to calm myself down (as much as I possibly could) to talk things with you when I picked up the phone. But oh, behold!!! It seemed that you were the victim here because you friggin' SHOUTED at me about the Wednesday's thing. Do you have any common sense at all? My sister is C-R-Y-I-N-G. How fecking often is it that she C-R-I-E-S?!? Do you think that she will be in the mood to sit through even half an hour with you?!? She will be faking every smile and laughter and that's gonna make me so darn fecking sick.

Yes, the dinner was important. But I think my sis' feelings count for more. Obviously, you were on a different wavelength.

And no, I don't find it rude at all for slamming down the phone when you were wishing me a Merry Christmas (so sarcastically, may I add) because you deserve it.

If you have any conscience in you at all, you make sure you pay my Dad for it. It's more than a fecking hundred bucks. But oh right, you have spent all your money on your never-ending wants. Typical.
