Lately I've noticed a few men I know (late 30s or early 40s like me) seem to be "flirting" with me in an odd way....bumping into me (quite hard) on purpose or on one occasion grabbing the back of my bike as I cycled along unaware that he'd caught up with me...it's happened twice today already.
These are men I know incidently...both of today's "incidents" were in the street and the shop...I know the men...parents of DC friends...it's happened a lot lately!
What am I doing? 
I'm not sure I like it!
