I definitely think that some topics or pranks should be off limits on April Fool’s Day. Sometimes things can trigger people’s anxiety, or trigger a bad memory that had happened to them. For example, let’s say someone is very claustrophobic, and for April Fool’s you decide to lock them in a tight space and then pretend you can’t unlock it or something, you won’t know how they’ll react. Your friend could be having an extreme panic attack or possibly a mental breakdown and you’re sitting there laughing about it. Then, imagine what would happen if they find out, it could possibly go two ways: one being that they laugh it off and start plotting your death in secret, or they get really mad at you and could possibly end your guys’ friendship and/or relationship.
