If you don't make it another week, are you postponing the First-Of-What-Will-Soon-Be-An-Annual-At-Tax-Chick's-Free-Republic-First-Thursday-In-January-Undead-Thread-Potluck-Supper until the first Thursday in February?
You’re going to have to choose another day of the week: on Thursdays we have Cub Scouts.
Aside from that, I could have the baby and host a potluck dinner at the same time, as long as some guest is a nurse or paramedic.
