Today is April 1st, which is otherwise known as the worst day on the internet. Everyone thinks it's funny to tell plausible lies, and everyone thinks it's my fault I'm upset because I should have known better than to believe them.
Fuck that noise, I say. Do not wilfully damage people's trust in you. Put on a silly hat, or make your lies so utterly outrageous that they cannot possibly be mistaken for real. The onus is on you, as the perpetrator, to ensure that your pranks are not harmful. You do NOT blame the victim. Ever. In any situation.
