I've got a sister. Her name is Kate. She's three. She has got many
toys: four balls - red, green, blue and yellow; three puppies - black,
white and grey; two brown monkeys, a yellow giraffe, a white bear and
two nice dolls. Do you think she likes to play with her toys? No, she
doesn't. What she does like is – she likes to play hide-and-seek with
me. Do you know the way she does it. She hides under the table and says:
"Helen, where am I?"
I say:

"Are you on the chair?"

"No, I'm not"

"Are you under the chair?"

"No, try again."

"Oh, Kate, I try and try again, but I can't see you!"

Then she runs up to me and says

"Here Iam!".
This is the way my little sister Kate plays hide-and-seek. Isn't she funny? Как читать на русском текс +перевод.
