everyone that I spend a decent amound of time around definately has a unique scent. I know my sisters, my dad, my mom, both grandmothers and a few cousins by scent. I DEFINATELY know my gf's, and oddly enough i know both my parents beagle and my older sister's german shepherd XD and of course some of my closer friends.
Thinking on it now, i guess it is kind of unusual to know someone by scent, but ive been able to distinguish family's scent for years. (granted i have to be within normally 3 feet... but still...) i didnt notice other people's scents until high school, when i was almost overwhelmed by the multitudes of scents coming from different directions. I think that i was in a partial sensory shift at that time though, because my sense of smell has not been that sensetive SINCE then.
but yes, i can distinguish scents on people![]()
