I was thinking of the phrase, "You made your bed, now lie in it." So I thought someone could say "Make your own bed!" to mean, "take responsibility!" or "deal with it!" That kind of thing.
I literally wrestled with figuring it out for a few minutes before posting, and the actual meaning did not dawn on me until I was writing that post!
I usually text in whole words and very rarely use acronyms, so it's a learning curve for me. Is MYOB a common used one? I don't even know!
Glad I got folks laughing.
