On the way home, I remarked to the PH how upbeat and outgoing his mom seemed and mused that maybe it was because I'm not used to spending time with her without her husband around. But the PH thought differently: "It's probably the drugs."
Lo and behold, when I called her today to see how she's feeling, she was giggly and cheerful, and when I said, "You sound like you're doing well," she replied, "It's the Percocet!" and start giggling like crazy. I guess the PH knew what he was talking about after all.
