<human>: Give me the gist of the text in a nutshell

My stepson is almost 5 and has been asking me to "do his nails", because he sees me doing my own. He thinks it's cool and is always checking to see what color I have on. 

Honestly, his dad and I couldn't care less if our son wants his nails painted. We've considered painting them for him on a weekend and then removing it before school, even, but don't know what to say about why it would have to come off. We are pretty sure his teacher would say something, and likely the other kids in his class, too. 

What do you do/say? "You're likely to get teased because that's a "girl" thing?" We don't want him to think "girl" things are negative!
<bot>: Stepson wants to paint his nails, we (parents) couldn't care less but realize he's likely to be made fun of or told "that's for girls" by his peers. Don't know what to say.
