Input: Text: happened a while ago but i still cringe. when i was 14, my brother and i used to have a running conflict in which we would hide in our house and ambush each other. he'd got me pretty badly earlier that weekend and i was out for revenge.

so i found a perfect spot in a cupboard and waited. like a predator, i wait for my prey. "this will be it", i told myself. "this time i'm really going to get him - and get him good!"

finally i hear footsteps and what i assume is my brother's voice (it was quite muffled behind the door.)

so i lunge out, roaring and i really go for it. "arghhhhhhhhhh!!!" 
eyes reeling, ready to leap on him.

..much to the surprise of the estate agent and group of potential house buyers who all shriek and  jump out of their skins in shock. one old lady looks like she's about to die right there.

i had completely forgotten that my parents had an important viewing that day for our house. 

red faced and speechless, i walk away slowly, with glares all round and the estate agent swearing under her breath.
