So we told my folks I was going with K. to her Dad's and we told her family that I was going my family. K. was mainly planning to spend the whole holiday adoring her infant niece anyway, so she didn't really need me to go with her.
But last night K. suffered one of the vertigo spells she sometimes gets and isn't feeling steady enough to drive. So, it looks like I may be driving down to Maryland with her afterall. Or if she's not feeling well enough to even be a passenger, we'll just have a quiet little Thanksgiving here in the city.
