"Gee, I didn't know the gun was loaded."
How in the world could she THINK that she dropped the child off at daycare? Does that mean that she's having hallucinations strong enough to make her believe that she made the stop at the daycare, exited her car, removed the child from the child-seat, walked into the daycare, handed her child over to the care-giver, walked back to her car, got in her car, started her car, and then continued with her journey?
If that's the case, she needs to be committed to an asylum as a danger to herself and the rest of society.
