Parents' nights vs marking

Can't decide which of these is more evil. They're both fairly excruciating. What they have in common is a) pulverizing tedium, b) they provide frequent occasions where you're confronted with evidence of your professional irrelevance.

What parents' nights have going for them is that they happen less often.

What they have against them is that, unlike marking, you can't execute your responsibilities with the aid of good things like fags, coffee, and central heating.

I can't decide. All I know is it's parents' night tomorrow and I would be extremely grateful if someone could write me a note saying I don't have to go.
