Presta valves. Hate 'em

I have a bit of a love hate relationship with these valves. I was just starting to like their little twisty knob tops but then I got a flat on my way to work wednesday. No problem. I was on a bus route so my bike and I caught a bus and made it to work. Patched the flat on my lunch hour. Had a little trouble, like usual, wiggling the air pump tube off the valve stem and heard that sickening sound - a big swoosh of air as it escaped the tire. I immediately knew what I did. I tore a hole in the tube where it's attached to the valve stem. Again! It's at least the 5th time I've done this. Someday I'll get these darn Presta valves figured out.
