No, not THAT first time.
When was the first time you saw something in this trade that made you say, "Woah... That is amazing! I want to work on stuff like this!"
It just happwened to me yesterday. I had the privledge of working with one of the journeymen in our company at a store with a central plant. I was in awe standing in a room where an evaporator coil made up one wall and a 12' tall blower assembly.
Eh, maybe I'm just strange, maybe simple things amuse me, or maybe just a bit of both.
