Is there an option for "maybe?"

I've discovered that sometimes, when I take my BP out and other people are holding him...if I'm close by, he'll seem to want to come back to me (via stretching away from them to me). The only thing I can come up with to explain this is that, over the years, he has become familiar with my body scent and associates that with security, ergo, he is more "secure" with me holding him rather than someone else.
