Knowing me, I will probably ask everyone if they are a minor or not LOL.

I just don't want to get screwed over, I can see the case now.

Judge: "So you found it acceptable to sell a potentially dangerous python, online, without knowing if the person you were selling to was just a deep voiced 14 year-old boy?"
Me: "Well, I asked him if he was over 18...."
Judge: "Did you get a signed document stating such? He says you never asked him."
Me: "Uhh, well, no..."
Judge: "Enough, stick a fork in me I'm done! You are being ordered to pay $1000 in fines for damage, $500 for mental anguish, and $5000 for selling a dangerous animal to a minor *BAM!*"
