I believe in order to have a paypal account you have to be over 18 because you have to have a bank account and all the banks I know don't open debit accounts for people under 18. I thought you were the guy too, haha, can't imagine such a pretty girl vaping from smoking! BTW, you have a nice looking family.
Just sounds like someone wanted to get a live version of you, freak. You did the right thing by not showing your id and the next time someone questions your age tell them they can verify it with your method of payment. I wasn't carded for years, last time I got carded was on my 38th birthday, I proudly whipped out my ID, and I kept thanking the woman that asked for it too! When I buy alcohol I hold it in hand hoping someone will ask to see it, they never do anymore.
