My friend is always so serious, I want to play a practical joke on them to lighten the mood. How can I do this without them getting angry?

You could try leaving a few cards around with funny messages or hang up fake decorations to surprise them. You could also set up an appointment for them to meet a stranger who turns out to be you dressed up in disguise. If they are not too angry, you can apologize and explain that it was all in good fun.

You could put something silly on their chair when they are not looking, such as a hat or a fake plant. You could also put together a surprising gift for them that highlights some of their interests and embarrass them if they reject it.
