I was driving ATL to work for 9am the other morning - I frequently do this, that's not the lesson - when I noticed some unusual puffs emanating from the front of my car as we stopped at a light. It wasn't cold but I thought it might be condensation evaporating. It didn't stop, so I popped the hood in the parking lot and then called Tarzan because there was some hissing coming from a plastic part I wasn't familiar with and the steam was much more evident. He said do not pass go, do not collect $200, drive straight to the mechanic and pray the car doesn't explode on the way. This sounded dire, so I quickly and carefully drove it over without any incident.
Turns out my car had busted it's thermostat so I didn't know it was overheating and during that time it cracked the hose connection to the cooling system and the radiator had to be replaced and lots of other things and they kept my car for a whole week figuring it out. But the morning I dropped it off Tarzan was already at school and couldn't come and get me so I took the bus and then walked the last two blocks home.
That'll teach me not to leave the house without a bra.
