Ugh! Annoying! Mind your own business. 
That used to be a pet peeve of mine too. A parent would interject comments or question something I was doing, even if it didn't involve his own child/ren. He did that several times and it seemed to only be this certain parent. Really nice guy, both he and his dw were super nice people, but he did make me feel intimidated many times.
