I'm planning to spill some Mountain Dew on the church's kitchen floor and I won't mop up the mess; I'll just leave it be and won't tell anyone.
That's really rude. What makes you want to cause a mess in the church?
God is always mean to me and demands so much from me.
You shouldn't intentionally make a mess, but if you do then you absolutely should clean it up. If you just leave it, you are forcing someone else to take time out of their day to clean it up. That's very inconsiderate.
But I will be the one to clean it up when someone says something.
You should never just make messes on purpose and you should always clean up after yourself when you do. It's the mature thing to do.
