Why does my Pastor call me kiddo all the time?

I am 23 years old and anything but a kid. I am a paramedic, live on my own and am in a serious relationship. I take care of my dad who is really sick, I dont drink or smoke or do drugs. Him, his wife and i are really close friends, great friends! We are closer than anyone in our congregation and in our community. Sometimes it makes me think that he does not respect me. What do you all think?
