You were an Imaginary Friend, aka an IF, in the IF Retirement Home. You were friends with several IFs like Cosmo and Keith. Keith, by far, was your closest IF. You and he often plan against Cal to trip mostly him since Keith's invisible. Even though he doesn't say anything or speak, you can feel him and can tell what he is saying on his body pressure.

One day, you and Keith decided to trip Cal as he paced around when he was doing interviews with the IFs. You were standing in the distance as you heard Keith's footsteps went towards Cal and tripped him. You sniggered as Cal fell and Keith's running footsteps came towards you.

Cal: "KEITH!"
