Random, but i paid for fanclub membership on Darren Hayes' official website, and he was in chat 4 nights ago (which you can only go in if you're a fanclub member - i paid £25, it's $35 for membership), it was awesome speaking to him (he high fived me heh). Anyway, one of the super fans (i'd never consider being a super fan - he's like followed Darren on sooo many tours its unbelievable) called Ash, kept calling Darren "Sir" and i just kept peeing myself, it's just such an odd thing to call someone, especially someone like Darren who is probably the most normal, down to earth celebrity who you could ever imagine chatting to (his goodbye was "Love to all and lots of inappropriate fiddles!" which i lol'd hard at - he's gay and totally shows it - love him!) so to call him sir is just..well..funny.
The only time i ever called someone sir was in school, and that was because i had to, but i used to try and get around it and call them Mr/Miss/Mrs (insert last name) as i always felt like i was in the frickin' army when i called someone sir/miss.

Anyway, short story for you.

Hope you manage to fix your bike (or get someone to help you fix it), and feel better soon.
