A few months ago, i was riding my bike and a person stepped off the curb, causing me to swerve and ultimately my bike to come out from under me in a crash.

As I was laying on the ground the guy came up and put his hand on my back asking if I was ok. It was the first time someone had touched me in like, months, and it was inexplicably nice. Just a concerned person, showing their concern.

Which is not to say, everone go out and touch everyone, but, it was nice and it really struck me.
