Sep 14 Word of the Day
Micro marriging is when your partner manages your personal day-to-day tasks with you much like a Micro Manager at work.
Wife: “Have you put the sheets out to dry and put the towels on?”
Husband: “Yes. You know I am a grown adult also used to live alone so you do not need to micro marrige me”
