I was kind of afraid that some might think that once an hour is a lot (yet, when we're driving cars, that's what is recommended). However, I really think the key is, no matter what our needs, to try and be courteous at all times. I always smile and apologize when I need to get out, and I'm not thrilled with having to bother someone, but I'm just not sure what else to do (I did acquire DVT a few years back, so I'm particularly suseptible to getting it again, which is why I'm rather religious about getting up).
