Here’s a piece of advice for anyone on social media. Do not befriend your parents. In fact, delete your Facebook altogether and just let your parents have that one. The last thing you want is to post an inspirational quote on Facebook, only to have the person who gave birth to you also be the one who put you in the burn ward.
