Sorry to be a bragging parent but I think this is appropiate for FHOP. I am proud to say my kids actively look for other Prii when we are out and about. My 5 year old shouts out "Pwius" and if it is 2010 he'll say "2010 Pwius". My 23 month old child with a severe speech delay will also chime in and say "Eeius". We thought the little guy wasn't able to recognize the cars on his own until he looked over at a magazine his mom was reading, pointed and said "Eeius." Oh my 5 y/o is very patiently waiting for a "Pwius" minivan.
Haha, awe. When I used to have my Prius, I'd always wave and smile at other Prius drivers. I still do too. Whenever me and my dad go on trips, we start by guessing how many Prius' we'll see, then we'll count them and one of us is a winner. Oh how I wish I had one again.
I used to count boom-trucks, those big ones with the buckets on ladders that the telecoms use to fix poles. Apparently it used to scare the crap out of my parents when I would scream "BOOM!!!" whenever I saw one. And offtopic, but @That_Prius_Car: Your new avatar freaks me out... It is like you are sliding into an abyss cartoon style!
