I tend to be very logical and literal. If you tell me something, it needs to be grammatically correct. Not because I am the grammar police. But because I hear everything that way and react to it that way.
If you were to make this statement:
“Go to the store and get a bottle of milk. If they have eggs, get six please.”
I would go to the store check to see if they had eggs, if so, pick up 6 bottles of milk and bring them home.
This has caused much strife in my life and even more when people realize my resolution to the statement is absolutely accurate even though not what was meant.
