Graduation Looms

We received a senior parent letter, telling us about paying for caps & gowns for graduation, when graduation is tentatively scheduled (barring any more snow days), and senior prom. June 19 is the potential grad date. I've been reiterating to my son to pass English & Sociology, because this is it! He knows, of course.
Until June 19, I'm holding my breath. Meanwhile I guess I'll pay for the cap & gown & if he by some chance does not graduate, he can pay me back (it's only $50).
If he does, however, we are having a party!!
