Me and my four year old were grocery shopping. He was saying all sorts of cute things to people and being very polite. People were really amused by him it seemed. 
Kids are really cute at that age.  Embrace the cuteness while you still can!
I will for sure! Kids are the best, are you a parent or planning on being one ever?
No I don't have any kids but I teach so I have other people's kids to fill that space in my heart.
