runner's thighs

The other day I was trudging up the steps and steps that are at every subway station in this city...God help disabled people..

I came across an older man with a trolley...trolleys are like substitutes for cars here...it is even called 'the pony'...it is a modern day packhorse for moving house on the subway...anyway I asked him if he needed some help with his trolley...

'Oh no, mumma, I couldn't let you. It's a macho thing.'
I thought fine, suffer in your pride...

So I was on the platform about 5 whole minutes before he got to the top and then he said to me,

'Could I ask you a question?'

'Sure'

'Are you a runner?'

And I thought like 'Are you married?' that my lie would shorten the conversation...so
'Nooooooo...'

'Oh. I think you should give it a go. I think you would be really good. Look at those thighs. They are real runner's thighs.'
