One day we were working with prepositions with 3rd year students (seven year-old students).

I asked them: - "Who is sitting behind you?".

One girl answered: -"Rocío".

A boy replied: - "Mica",

and the other boy, called Ian, said: - "Nobody".

I added: - "The wall",

and he replied: - "The wall is standing, not sitting".

I couldn`t agree more!
