If there's a next time that Angie reaches out to touch the machine you're on, "playfully" smack her fingers and say something like, "My machine! Don't touch!" Don't let her make you feel bad; you're doing your own thing and though you were disappointed in yourself for not going to the gym as much as you wish you wanted to, you are "there" and that's better than it was! A good, free, online site I belong to that might help keep you company with the gym thing is http://www.sparkpeople.com. People there will thoroughly understand how peeved Angie made you and be able to give you support and ways to help yourself get to the gym more often and blow right by Angie!

I'd try to feel bad for your boyfriend's mother. If she's just sitting all day, watching TV at 70, she may well be depressed; doesn't sound like much of a "life" and I'd see if I couldn't engage her a little, give her reasons to get out of that chair? Is there a local senior center? There's lots of classes and other people she could meet and maybe do stuff with and then she won't be so bored/"dead" that she doesn't even care enough about getting/wearing her clothes from the dryer. I don't know the layout of the home, but she may not have done a full load because carrying all that up/down any stairs and messing with it might just be too "hard" for her. After one's mid-50's life does become a lot more difficult in terms of energy and having the "strength" to do stuff and all that sitting is eroding what few muscles she has left! Just as you have trouble getting to the gym and then on the machines after you have been away, she's having similar trouble with her everyday life; what does she have to "do"? There's no work or boyfriend/companionship and it certainly doesn't sound like she has a hobby. It's much harder to come up with motivation when there's no where to "start" (I'm 60 and retired and struggling with those problems now myself).

But besides that, it is her dryer! If you aren't paying her for the use of it, I'd at least be cheerful about occasionally clearing her stuff out and putting it on her bed/in her room for her. It's not like it happens that way all the time?
