Not sure whether to be concerned or annoyed

Summer teaching.

I have one student in one of my classes who has e-mailed me no fewer than four times (in a week and a half of classes) to try to set up an appointment to see me. They have missed every one of them; the morning it's scheduled they e-mail and push it to the next day.

Which makes me think this is a Highly Avoidant Person. I know about this, as I have avoidant tendencies. (Right now, I have all the receipts from a work-trip on my desk, and I MUST fill out my expense report by the end of this month if I am to get any money back, but I just feel so meh about dealing with the minutiae of paperwork that that involves, and I feel very especially meh about the e-mail I will probably get back telling me how I did it wrong and to go back and redo it. Because they change the rules every year.)

Anyway. I don't know what I can do - for that matter, I don't know if I SHOULD do anything - if it's someone being avoidant. I mean, this is someone who's technically an adult, and frankly, one thing I learned in a hurry in college is sometimes you need to woman up and do the stuff you really don't want to do, because being an adult means that it's on you to do those things.

But it's also possible this person is just the specialest of snowflakes, and keeps finding stuff more "fun" to do than to come in and see their boring old professor and find out that the reason they're doing poorly on tests is that they aren't studying more than an hour in advance for them. Or whatever. Or it's someone whose life is in such a shambles that they can't make it to appointments.

But still. It irks me to set aside a time, and then find out, "NOPE! Set up another time tomorrow." (At least this person has the kindness to e-mail me in the morning, unlike some students who set up appointments, never show, and I'm left sitting there until I feel "enough" time has elapsed that it's okay for me to leave.)

People are funny though. As avoidant as I am about "difficult" meetings, I feel like it's a greater embarrassment to reschedule - so I make the meeting and by God I show up to it. (It may take me forever to get around to making the appointment, though).

Also, attendance has been worse this summer than in the past, which makes me apprehensive. Each week in the summer is like 2 weeks in the regular semester, so missing much can really sink a person fast. And I don't make my summer classes "easier." I know some profs do but I feel like I should make the class as equal as possible to the regular-semester version.
