When your husband lies to you...?

What do you do? It was a Friday, and I was out running errands and thinking about dinner. I called his office and his secretary said that his computer was off, and that she hadn't seen him for a while. When I finally got a hold of him he told me that he was in a meeting with some people at his office. I questioned why he would turn off his computer if he was still at work - he started to act weird, so I got suspicious. I kept bothering him and he finally told me that he left early to hit some at a golf course by the airport. I asked with who? He replied, by myself. Well the thing is that we have a golf course in our backyard. So why would he drive all the way out to the airport to hit by himself, when he could do that 1 minute from home? After much pestering, I got him to admit that he went with some people from work. His lame excuse was that he didn't want to upset me because he had gone golfing the day before. I don't care about the golf, I care about the lie.
