Lettuce Talk About It
Some jokes will now be only for you and your partner after you join together. Some of these remarks may appear to others as lunacy, yet both of you are aware of how you preserve your time. For this pair, punting lettuce is an inside joke. Perhaps they despise it equally?
I don’t get it, but we are not supposed to understand this joke. It is not meant for us. We must consider that her partner understands the joke and that they shared their amusement. That’s the charm of inside jokes: We have to believe her boyfriend was aware of it and didn’t intend to give her this lettuce to take it home himself.
