Years ago I worked with an English woman. Out of the blue she asked me "Do you have a rubber?". "No", I mumbled. (I didn't know her very well, so I wondered why in the heck she was asking me.) She continued "Well do you know where I could get one?". I said "Couldn't you stop at the drugstore on the way home?". "But I need it right now!" she replied. I thought "Oh my god she must be headed for the boss's office to screw him !" (He was the only male around). I was thinking the affair must pretty hot and heavy if she needed a rubber so badly and just couldn't wait, and was thinking neither one of them seemed like the type. My boss was about 65 and she was 24. After a few minutes I realised she was talking about an eraser.
