K is hot!

Our neighbor boy is 4 (nearly 5) but he approached K yesterday and told her, "You're hot!" K's response was, "Gross!!!" I hope she keeps thinking gross. About an hour later the little boy came over and said he had something for K and it was a flower he had picked out of his flower bed. Oh brother!!! Is this how it all begins and never ends? I am not quite ready for the boys approaching her already.
