something in the air?

there's something about making ridiculously long flights to england and being frantically busy on arrival. when we come home again its like my brain's been rewired in some way. the first time i went i started to eat solid food while we were there, and then to sleep through the night on our return. not to mention growing some hair, too.
the second time i pretty much learned to walk.
and this trip? i've finally got words and sentences sorted out. whereas mom used to point out buses and the like when we were out in the car, now i give her a running commentary: " i see a cherry picker. Ooh, another cherry picker. i see a yellow backhoe, there's an orange excavator. it's a dump truck. there's another dump truck. look mom, a crane, two cranes....."
i'm not quite sure why mom looks around at me as if she's going to strangle me any minute. isn't this what you're supposed to do when you're out in the car? it's what mom and dad have been doing for months!
