Birthday idea?

Hi ladies this may be a dumb question but I’ll ask anyway. Would it be weird to get professional pictures done for my 20th birthday?

I see them done all the time for 16th, 18th, 21st, and even 30th, but I’ve never seen them for 20th. I know nothing “exciting” happens, but 20th birthdays are so unappreciated (I work in a Hallmark store and they don’t even make birthday cards for 20th!) I mean you’re officially not a teenager anymore.

Also, the only professional pictures I’ve had done were just a few yearbook pictures for my senior year and those were mandatory and I had braces🙄

Would it be weird though?
