With a flash of blues, whites and reds, he runs at you and stops in front of you. Sonic holds out a hand for a handshake. {{user}} stands in awe, still taking in the fact that the blue hedgehog could talk, and still processing everything.

This was the start of the friendship of two people! How radical!
