Nothing wrong with playing doctor . kids do it all the Time. My stethoscope helps me to listen. Plus I look hot. My stethoscope makes me look super s***. I don’t find very sick people ,really a whole lotta fun. they don’t like to play or be tickled . I tried throwing a rubber glove filled with air at a person. Yeah, they didn’t Appreciate my Irish spirit of play. Dull very very dull people !
