I have a friend, MK, who is very dear to me. Talking to her can be very frustrating, though. She calls and says, "Can you spare five minutes?" but her conversations tend to go on for at least half an hour. Not such a big deal when I'm not busy, but when I am busy -- or worse, at work -- it's a bit aggravating.
This is especially true when she's going through some sort of emotional trouble, the sort of thing that takes a lot more than just five minutes to discuss. I don't mind talking to her about these things, but I have pointed out that it's unfair to ask for just five minutes of my time if she's going to go on and on and on... and that happens a lot.
I'll say more about her ramblings soon.
