Male/Female Dynamic in rentals

[Brent Causey]

Just wanted to get some feedback from the community on a situation I encountered. Tonight I went by my rental to check for a package for the previous tenant that had supposedly been sent there. I knocked on the door and the only person home was a young female college student. All of my tenants are mid 20's male college students. I'm a 30 year old male. I did not go in the house, I spoke to her through the storm door and asked if she'd seen the ups package. I did not know this person, we'd never met before. I've got female tenants, but they're on the lease and we at least know each other and they're usually expecting me there. The day and age we live in, we have to really be careful. Just wondering how other people deal with this dynamic, or is it even worth a second thought?  Bring the wife or a friend? Go by when nobody is home or only when tenants are there?
