I used to always sing in the shower; but I seldom do that anymore. Maybe because I try to take very short showers nowdays.
When I was a kid, my mom and dad always sang together, and especially when we were driving somewhere, we sang in the car.
I loved hearing them sing the old-time songs like “Old Black Joe” . I was just singing that to myself (quietly so as not to disturb my husband) in the car the other day, and thinking how long it had been since I have even heard that song.
Not since my folks used to sing it, I imagine.
Anyway, when I had my own kids, we did the same thing, and they grew up singing Johnny Cash, Waylon Jennings, and Kris Kristofferson songs.
I still love to sing, and I think that it does not require being “good at it”, it only requires that a person enjoys the singing.
