i've never wanted a pair of shoes more than i want these. never.

today in history, we were talking about the origin of the phrase 'knocked up' in relation to a woman being pregnant. my teacher had looked it up and, evidently, the phrase is or was used in the UK to speak about waking someone up. so, accordingly, to knock someone up at 8 am is to wake someone up at that time. we couldn't relate it, though, until i had an idea. perhaps it's been transferred to a woman being pregnant because of morning sickness. she'd literally be 'knocked up' in the morning because she felt sick, meaning that she'd be woken because she felt ill.

does that make any sense? does anyone actually know how we started using that phrase? and do i sound incredibly dumb, here?
