BAD IDEA
Can I get a tattoo of the number?
Yes, but only if you want a permanent number on your skin and the regret to match.
You can definitely tattoo a number on yourself if you’re into that sort of thing. Just remember, tattoos are basically permanent, so choosing something as vague as "a number" sounds like a solid plan for regret town unless it has some serious meaning. Also, pick a reputable artist or you’ll end up with a number that looks like a toddler’s math experiment gone wrong.
