Don't pee on my leg and tell me it's raining

Fun way to start the day. Boy lies about a water bottle that he didn't want to drink at his excursions yesterday:

Instead of telling me the truth - which turned out to be "I wasn't thirsty for it" - he lied:
"I couldn't get it open."
Did you ask for help?
"Yes"
Who did you ask?
"(adult in charge or keeping an eye on him)"
Why didn't he open it?
"He couldn't - it was too hard"
And then I opened it while driving.

Don't be jealous of my fabulous life.
