We were watching an old episode of Harry's Practice when DS (renowned for his imaginative play) decides he wants to play Dr Harry...off he goes to get his hat and shoes. He comes back and asks, 'Hello. Do you have a pet with a problem?'
Me: 'Why yes. I think it's in here' and head to his bedroom to get a stuffed toy. I hand him a toy dog and say, 'here's my sick pet. Can you help her?'
DS: 'actually, that's not a real pet. It's just a stuffed toy. Where's your real pet?'
Me: 'uh...?'
DS: leans over and picks up an invisible pet....'Here's your pet dog. This (touching the toy) is JUST a pretendy toy.'
