Sam !!!!! Are you nuts? You can't do stairs!
How many times have I told you that you shouldn't come down the stairs on your own? What do you mean dad? I was at the top of the stairs, I pushed the gate open and I came down the stairs. Ta da, easy.
You're going to hurt yourself Sam and then we'll have to take you to the vet and you won't be able to walk outside with your wheelchair. Hmmm...well if that happens, you could pull me around in my wagon.
Arrrugh....Sam - you're making us nuts. Please don't come down the stairs on your own anymore. You're freaking me out. Promise me you won't do that anymore Sam.
Yeah, yeah dad :)
