I have a headache

My head hurts.

1 hour earlier:

I see the door is open to the porch. My food is on the porch. I dash for the door. Ouch! 

“Oops, sorry! Didn’t see you boy. You can’t run through the door when I am closing it.”

½ hour earlier:

My foster dad opens a cabinet door. I wonder if there is food in there? Ouch!

“Bart, sorry! I didn’t see you again. You can’t stick your head in every open door…”

5 minutes earlier:

Wow, the cold box with food is opening! It smells good in there. I move toward the light. Ouch!

“Oh Bart, not again! Sorry, but get your head out of the refrigerator…”

Now:

Hey, I think the closet door where they keep the treats is open…
