I remember when I got my first tattoo. My family was all cool with it as long as it was somewhere I could cover up - I of course chose bicep cause that was the cool guy spot. Fast forward 20 years and I have mostly full sleeves and no one gives much of a shit about them. People I've just met barely even ask about them anymore.
My 9 year recently started showing interest in tattoos, and my wife told him basically anywhere but face and neck is cool. Of course he was mostly interested in face tats cause Post Malone and the cool rappers have them... But, I figure by the time he's 18, tattoo's will probably be completely uncool (like having a single ear piercing - left ear cause we aint homos) because they will be so prevalent that not having them will be the better way to stand out. Plus there's going to be a lot of old fucking boomers limping around with full sleeves and shit.
