...then came back and did his 'warming-down' bullshit by his desk. To rile me further he started angling for approval/praise of his gym action by steering conversations in a kind of fitness direction...

Him: "So Jon, you still cycling to work?"
Me: "Yep" (as my bike being outside the office everyday would suggest...)
Him: "So Andy, enjoy your walk at lunchtime"
Andy: "Yep, served it's purpose - I got my lunch..." Good work Andy, don't give him a platform...he's struggling...or is he...
Him: "Cool...yeah, i only managed ten million bench presses today, i'm slacking"
Me (thinking): Hang on? How did that happen? No-one asked you about your gyming, now shut up!

At this point he's stretching his hamstrings like it's 2 minutes before kick off.

AND he's a vegan. Jeez.

Irrational anger?
