Signs it is hot in your apartment:
1. There is a "heat emergency" and the heat index (ie the 'real feel') is 105 degrees, yet when you step outside it feels so nice and cool!
2. things in your freezer are melted.
3. you can stay up until 3am and not feel tired, because the thought of trying to sleep is incomprehensible.
4. you don't turn on any hot water in the shower, but by the time the water hits your body it's warm.
5. ice in your glass of water melts before it has a chance to cool the water.
