Confused

I left the South Texas border town where I work last Fri. to go home in Central Texas. The low temperature that night was below freezing, so I dressed warm and left the heater on in my apartment. When I returned today (Monday) I was wearing shorts and a t-shirt. It was 85 degrees and people were sunning themselves by the pool. I immediately cranked up the A/C. 

There are a lot of things in this world that confuse me. The weather shouldn't be one of them...
