How old do I look?

Okayyy so at work I was a host and I had an old couple ask me why I wasn’t at school on a Friday morning (I have college classes Mon, Tues, and Wed). I proceeded to tell them that I was a freshman in college and their response was “oh wow college, you look like you’re 15!!”. I just recently got a new job as a server and the minimum age you can be is 18. I’ve had people guess my age at work and they say I look 19,21, and even 22. How old do i look?
