It's interesting to see the different directions in which boys and girls' suits go as they get older. My best friend and her husband have a daughter the same age as my son. We regularly have Sunday dinner at their house and frequently end the night with a dip in their hot tub.
When the kids started wearing swimsuits, my son was in a brief and their daughter wore a one piece suit. My son switched to shorts and then boardshorts. Their daughter eventually started wearing tankinis, then bikinis, and these days her swimsuit is practically a thong. He got more conservative as she got more, well, naked.
I had coffee with my friend and mentioned my son's Speedo interest. She started laughing and told me she had a confession. Her husband is a Speedo lover! We've known each other since our kids were babies, and somehow I never knew. I almost didn't believe her, but she pulled up a vacation picture on her phone and there he was wearing only a Speedo. He only wears them in private. My friend has always been a bit embarrassed by them, so he keeps them hidden.
We have dinner plans next Sunday, so I asked if she thought he could wear them while we're there. She said she'd ask. I got a text from her later that said: "Speedo Sunday is on!"
