Did he just...no...or....

Another weird thing about me (in case pointed object phobia alone is not enough) - if I hear someone kind of wheezing, I get an almost uncontrollable urge to cough. Rob was wheezing and coughing the other day and I was coughing and we both were laughing (because I have to cough) and then Conor sticks his tongue out and coughs. But it wasn't like a real cough. It was just shallow and weak. It was almost like he was imitating us. At five months? Could that be? He did it a couple more times, too. My son, the genius?
