One time, I gave my friend some money so he can buy a soda in a shop. He thanked me,saying he'll return it when he's able to, and went to buy it, and I remained where we were originally, waiting for him. He took too long to buy it, so I got bored and went home. Upon arrival, I sent him this text on Messenger:"I got bored waiting for you, so I got home. Return the money whenever you want. Enjoy.". His father saw the text, and because I don't use my real name on Facebook, nor do I have any pictures on my account, apart from the profile pic (which is a fanart of one very obscure videogame character), his father though that my friend was buying drugs from someone. He needed three hours to convince him that it was just me. I laughed like a maniac when he told me of that.
