My dictionary says it's a make-believe play.
My daughter asked me to play with her but I was drawing for my blog then.
She said it was OK and asked me to play a role of customer when I finished my work.
When she finished to prepare her 'bakery' with a cushion, toy bricks and toy money, I was still drawing.
Did she wait for me silently?
No, she began to practice selling, "I say, 'Hello. Well come to my shop.' and I use this machine, 'pee'. "
I felt uncomfortable and said, "I'll join you now."
Listening to her practicing, I came to know how she had wanted to play with me and I thought I had to join her in a hurry.
