A woman who can set tappet clearances...I think I'm in love

I went for a spin down to Mt Eliza this morning. Loved the ride, but I think I'm getting angry in my old age. After having some dude sit on my wheel for 15K's I turned around and told him to either do some work or F... off. He wasn't happy and eventually tagged onto a group of guys who overtook us. Does this annoy anyone else or am I being unreasonable?
