Are you busy?

So my grandmother called this morning while I was at work. We don't have a land line anymore, so she called my cell, and even though she understands it is mobile, she nevertheless assumes that I'm at home when I answer it. She'll probably remember later that I work on Wednesday mornings, and then she'll feel terrible: she hates to call when I'm at work, even though I tell her that if I'm busy, I won't answer. But she definitely didn't remember this morning. Here's about how the conversation went:

Me: Hello? [I say this like I'm answering a land line without caller ID, because that's what Grandma expects, even though I'm actually answering my cell phone.]

Grandma: [Long pause.] Ooh. [Like I've surprised her.] Jenny?

Me: Hi Grandma.

Grandma: Jenny, did you call me?

Me: Um, no.

Grandma: Well, I was just in the bath [by which she means 2 inches of tepid water in her tub] and the phone rang, but I couldn't get to it in time. Called Jackie because she sometimes calls in the mornings, thought she was at her exercise class but maybe not, so I called her to see if she called, and Bob answered, said she wasn't back from exercise yet, so it wasn't her. Thought it might be you, but you didn't call?

Me: Nope.

Grandma: Well, I hurried out the bath [which now makes me think she could be dripping naked next to the phone, like when she answers the "What're you doing?" question with an obvious mouthful of toothpaste muffling "Just brushing my teeth" because she's crazy afraid of missing a phone call] and put on a bathrobe real fast [phew] but didn't make it. Thought it could have been Jackie, but no, so I thought maybe you.

This continues on a loop for a while as she runs through previous missed phone calls and possible callers, reiterating how Jackie often calls in the morning but it couldn't have been Benita because she calls at 10:30 every night and never in the morning, etc. Then, finally:

Grandma: So I probably ought to let you go because I'm getting cold here. Are you busy? [Absolutely no pause for answer.] I mean I just got out real fast and put on this bathrobe.

Etc, with a diversion about her always impending haircut, until finally she does say bye.
