When I used to travel, the boy would indulge in what he called "boy's night". "What do you do on boy's night?" I'd ask. "Oh, you know...watch movies, eat my favorite foods, play computer games or just veg out" was the response.
Which always puzzled me because that's pretty much EVERY night at our house. But he would just wave it off and say it was somehow different.
I think I understand now.
Instead of moping around the house like a sad sack, I've planned a girl's night for myself. Something silly, frivolous and fun and wholly centered around my enjoyment and pleasure. [ed. again, no different from every other night. I am spoiled.]
