Fish and visitors smell in three days.

Summary

This quote alludes to the notion that the longer guests stay at someone's house, the more likely they are to become a burden or create annoyance. It serves as a warning to hosts that even well-intended guests can become tiresome after a certain period of time. The comparison of visitors to fish highlights the idea that, just like fish tend to spoil after a few days, guests can also overstay their welcome and start to cause discomfort or inconvenience.
