We're all a little atypical - we all have ticks, things we do we can't explain. Things we know are illogical, but we still do.
I, for example, never put on socks again before I wash them. Even if I've only worn the socks for 5 minutes, they get washed. Which means each week I wash something like 21 pairs of socks.
