There's no doubt in my mind that, all things considered, Olivia thinks her dad is the funnest person ever. It may be because he was the proud giver of her first solid food - ice cream - which even today is the best bribery tactic we have for getting her to do something. Or it may be that she gets to see mom all day long in all her moods, from quiet to loud, while her dad is always ready to play in the evenings when he gets home from work. So percentage-wise, dad time is so much more fun.
But this became abundantly clear when she first began using one of her favorite (though not widely-used) commands:
HANG UP.../TAKE OFF...
This is a time- and space-specific command, used solely when Nathan walks in the front door, either for lunch or after work or rehearsal. Regardless of where she is in the house (unless she is deep in a comatose sleep), she hears the keys in the front door and shouts "Daddy! Daddy! Daaaddy!" She then runs* from wherever she is directly to the front door and as soon as the precursory greetings of "welcome home" and "Hi, Olivia" take place, she launches into the following:
Olivia: HANG UP MY COAT (translation: Daddy, hang up your coat please, and then close the closet door promptly, otherwise I will do it).
Nathan: Olivia, do you want me to hang up my coat?
Olivia (ignoring the question): HANG UP MY SCARF.
Nathan: Okay, I'm hanging up my scarf.
Olivia: TAKE OFF MY TIE (this indicates that Daddy will stay longer, since those knots are a pain).
Nathan: Well, I need to keep my tie on right now (for lunch).
Olivia: TAKE OFF MY (work) SHIRT.
Nathan: No, Daddy needs to keep his shirt on right now.
The best time for Olivia, of course, is Nate's evenings off, where all of her commands are gladly heeded and, once changed into more comfortable threads, they romp around the house until bedtime.
*Running for Olivia isn't what you might imagine. The usual banter surrounding children walking is that once they begin walking, they'll be running before you know it. Well, we know it, and still no galloping. Running consists of a quick walk, maybe with a bit more bounce. Not that I'm complaining!
