Sometimes it gets so hot without air conditioning I would be lethargic and struggle to get anything done.  I hate how it is turned up so high in public places though. It is freezing in shops and restaurants. If I am spending the day outside, say at the park, I have to bring a coat for when I need to go in somewhere.  Probably the fault of fats who always seem to be complaining about how hot it is. Watching them sweat through tee shirts after a 5 minute waddle is both amusing and disgusting at the same time.
