dust in life

Yesterday me, my colleagues, J & A had lunch together.

J asked me and A "do you have dust in your life?"
I did not understand what he meant by dust

Later J explained "..dust settles on unused things.
Similarly, stagnated life could be referred to as dusty life.."

Also dust refers to cocaine especially when combined with mirror

I do not think I have dust in my life...

shoes & tyres

In US shoes lasts longer than tyres..
It's the other way in rest of the world
