A 'friend' of mine who moved away let me know that she is going to be in town next week and asked if I would be around. At the time she asked, I had no plans, so I said yes, probably.

She's never gotten back to me with specifics. I suspect she is just using me as filler, so I'm not feeling that guilty about planning a camping trip for this weekend. She was here a few months ago and kept me waiting an hour while she had lunch with her boyfriend -- so, yeah, very little guilt.

How long do you keep your calendar free for these requests? If you suggest getting together with someone on a weekend, how long do you wait for them to accept or decline before making other plans?
