I like they way Jame allow everyone to remove their profanities. He's being very understanding.
Matt, I hope your mum gets better. Hope everything will be alright. Don't bother so much about this now, your mum comes first.
Threadstarter, I understand how you feel when the seller didn't turn up and didn't return call. Try to feel for him. Try putting yourself in his shoes. I believe you don't want people to discriminate you just because you're young. Young people can be sensible too. Be more understanding.
Sidetracking a little, my girlfriend once told me this, "i wont marry someone who says ' i love u' to someone and then... says F *** you to another person with the same tongue"
It makes me wonder why she says that initially but I've grown to realise that what she meant was that I should learn to control my temper. Ultimately, a person's character will change over time. She probably doesn't want me to treat her well initially when I'm wooing her and turn into my usual self after we get married. Thus, I see the need to change to. Not just for her sake, but also for mine.
Start cultivating your habit now before it gets worse and you'll grow to appreciate your life more.
