ways to tell i'm not my neighbors.

...i'm potentially more courteous

When I am getting out of my car with a load of groceries, and then as I am walking towards the apartment building, I notice that two of my other neighbors are both getting out of their cars with loads of groceries, my automatic inclination is to prop the door open so that the other people don't have to akwardly set down their groceries, fish for keys, and then fumble their ways into the building, like I just had to do.

I am also inclined to do things like hold the elevator if someone is immediately behind me, with a large load of groceries, or at least send the elevator back down to the first floor once I reach mine, if said neighbor isn't close enough for me to reasonably wait. I do have ice cream melting, you know.
