it's a girl thing
I was standing in line at the grocery store by the office, and looked over at the till next to me. A couple of blokes were buying hundreds of chocolate bars - bags and bags of multipack Kit Kats, Snickers, etc. that must have been for resale or their office. The woman in front of me said, "That's an interesting purchase" and I said "I could do that, no problem." We gave each other a look and burst out laughing, knowing exactly what the other was feeling.
