I give rides to pilots in my plane (most of the rides I get from other pilots originate at their home airports and are planned well in advance such as formation flying, Angel Flights, or fly-ins).
I don't go to the airport to "hang out" with no formal plans - it is too far from my apartment to do so. If I'm there, I am there for a flight or a meeting such as Young Eagles, Angel Flight, a personal flight, to act as a safety pilot, to wash an airplane, to attend our monthly dinners, or to participate in the bombing. I don't just show up at the airport and hope for stuff. The first 8 months of my training, I flew roughly 1-3 days per week and not one person said "hello" at the gas pump, restaurant, or flight school. I was completely alone in my quest for my certificate. Then one day the airport manager / weekend manager came over to my plane and introduced himself, saying he'd seen me around for months. That was in 2011.
