Tips for writing a message
- Match the joke to how well you know them — save the savage lines for people who'll laugh.
- Short usually lands harder; a one-liner beats a rambling setup.
- Punch up, not down — tease age or habits, never appearance.
- Follow a joke with one warm line if you want to soften the landing.
- Read it out loud once; if it makes you smile, it'll work.
