You know you're tired when...

[MantaRay]

You crush your own weetbix up instead of your DS's weetbix. And don't realise till you start eating it and wonder what is wrong with the texture.

You enter your atm pin into the key pad on the day care door and wonder why it won't open.

You type your username instead of "bellybelly" into the url bar.

[MistyFying]

You get your kids ready for the magic show they have tickets for, drive them half an hour to get there, get to the door and realise it's actually on *next* Saturday poor kids.
