As I entered the parking lot and approached the car, I heard the quiet buzz of a passing insect... immediately followed by a soft impact on the back of my head. I reflexively started to reach up, then thought better of it. It was probably a bee. I could feel it tangled in my hair, struggling to free itself.
I've never been stung by a bee, but I've had one in my hair no less than three times. I do not react with surprise or horror when it happens. The first time, I thought it was a grasshopper (I like grasshoppers) and gently reached up to free it. It wasn't until I plucked the insect off my head and lowered my hand that I saw I was holding a bee. I let go of it very, very quickly. No sting. The second time, I felt it hit but didn't know it had been stuck there, so I finished walking home and was somewhat surprised when a bee fell off my head in the apartment.
This time, I just stood there, hoping it would go away. When Ken finally came out, I stopped him from getting in the car -- "Is there a bee in my hair?" I turned my head to show him, and the bee fell out onto the cement.
