It is unfair...Here is why...
If a man loves his woman, he should do some things she like. Sharing, that sort of stuff. So you are expected to suffer windows shopping, handling things, going from display to display, talk to no ends about those things, and do that practically all day.
But if a woman go 'shopping' with a man, and I used the word 'shopping' generously, we would just go into the store, grab what are needed, pay, and leave. What is there to suffer? If she want, she can always return and 'shop' the way she want, whereas a man would never voluntarily return to the store and do all those useless acts of 'shopping'.
The thing is...Even when I gone shopping for tools, I barely do 'shop' the ways women does. I might check out the new tools a bit, but I still do the same: know what I want, get it, pay, and leave.
