As an aside, and in reference to yesterday's anxieties:
Catering at my brother's graduation reception turned out to be rather painless. Set-up was easy, the food was great, reception started late (due to stereotypically long-winded graduation speakers..), and there were no awkward moments to be had.
This, I'm certain, is due to the fact that I put myself in charge of wine.
No one wants to burn bridges with the gal giving out the free booze.
