Whenever I whistle my Simon will come. Great way to find him but I think he also wants me to stop. If I keep whistling long enough he will jump up and cover my mouth with his body. LOL

Not sure if he is saying I know that is the signal for me to come so why keep doing it when I am here or I really don't like to hear it so stop already.

He just gets nervous if I keep doing it so not sure what his message is. If he enjoyed it he probably would not try to stop me.
