LOL!!
However, back to ummmm's, it reminded ME of something which happened ages ago. I answered a knock at the door, and a guy basically walked in and plonked himself down in the kitchen. I was flat-sharing at the time, so wasn't too concerned, as I thought he must've been a friend. After a few minutes of small talk, he started to make compliments about me, and alarm bells went off. I made excuses that a couple of the girls were due back. Had he been a real friend of theirs, he would've stayed, but he shot up and left. No idea who he was, or why he was there, but it makes me dither to think back to what might've happened.
