Hi there knotty, it's quite true what everyone else have had, so I'll just add, that there is no way to avoid the "stickys" as LikeMinds put it, there's always a chance to find new ones, but don't let them ruin your lifestyle for it, my advice would be to let it as a "great one time experience" with them and move on to a different kind of people, maybe they tell you now that they don't want to be pushy, but if they already started, probably they're just faking it to keep you there with them. I had a couple friend that sometimes would get mad just because I wouldn't answer on the msn for a few min, like it would be my duty to do it, (sometimes I just was doing something else on the house or was just a phone call) so, that's the kind of people that you don't want to get around.
Best luck, would love to see you more on the board
