Note to self: easy access to the internet is making me stupid. Instead of trying to figure out what YCPEATT meant, I immediately tried duckduckgo. When that failed, I tried google. When that failed, I spent a whole 5 seconds figuring out the initialism.
Ok, I'll bite: What does YCPEATT stand for?
"You can't please everyone all the time."
Many thanks. Like the answer to an NP problem it's obvious once you say it but I couldn't for the life of me figure it out.
