Doctor and writer aren't bad at all. My parents wanted me to be a doctor or a lawyer, but I had other ideas, really.
Lena is incredibly bright and stubborn (she got the latter from me). I hope she sticks with it, too. Valya thinks he wants to be an archeologist, but he's 7 and the ambitions change with the weather. He also got a ton of books on Egypt for his birthday, which probably is contributing.
I could talk your ear off about them and probably ought to stop, sorry. I'm like that babushka who takes out the roll of photos of the grandkids in the grocery store.
