Walk the Talk

It's funny how some people don't walk the talk. For example, someone tells you firmly, straight in the face :

I'm not going shopping.

And the next thing you know, you see that person in the same shopping complex as you, shopping.

Hoho.. I wonder would that person feel embarassed with what he or she said earlier?

P.S : Cracks me up each time when I think of the scenario. =D
