I don’t suffer fools gladly on any day, doubly so on April 1.
No “practical jokes”, please. Not now. Something fun and funny that doesn’t hurt anyone, fine. Hurt someone’s feelings or scare people, or just lie about something very concerning to folks… Well, that firecracker is going to blow a few of your own fingers off, at the very least.
Keep it friendly, goofy and fun.
Don’t be mean. Now isn’t the time to be a dick.
