*A casual conversation while strolling around in the mall*
Friend: You know I end up buying a lot of shoes.
Me: Thats cool. If you like something, just buy it. That's what I believe in.
Friend: But I have a lot of shoes and footwear.
Me: Hmm. How many?
Me: 70! Oh. You mean in your entire lifetime
Friend: No. Currently.
Me: (Of course I could not respond immediately. That is too much data even for a guy.)
Friend: But I don't think 70 can be called the correct number. There are a few that I no longer wear - about 5 of them. (pause) So how many pairs do you have?
