Oh! One more wonderful thing to mention, I took the boys to the zoo today and they were perfectly polite and respectful to all the animals. No screaming at or chasing birds to make them run, not tapping on tanks, no inappropriate behavior of any kind!!! I am so proud! (Personally I wants to strangle several other children for their bad manners and disrespectful behavior, but I refrained. Yay for me. LOL)
