Here is a thing I do. Every Sunday, or almost every Sunday, I do my nails.
Here is why.
First, it’s cool, I like it, I like colors. Second, It has become a thing, the girls have done it for a while and one day I was asked me to join. They pick the colors and all. My wife does my hands though, the girls do my toenails.
But I think the most important reason I do it, is because I want my girls to know that not everything should be gender-specific. Not everything is for just for “boys” or just for “girls”.
But then, when I am at work or somewhere else, I always get the “Oh you must have girls”, every time they see my nails, and I roll my eyes. Some give me compliments and I like that :)
