Input: Text: the morning started so well. i woke up 30 minutes early without an alarm and had a pleasant breakfast. the sun was out and the day ahead looked promising. 

i was in the bathroom, playing loud music. i'd just lathered my face and about to take the first scrape when a loud grunted "oy" comes from the other side of the door. i jumped out of my skin! i was seriously startled! at this point i guess the "fight or flight" mechanism kicked in and everything seemed simultaneously in slow motion and at the speed of light. i opened the door and saw a man standing there and while still processing the fact that it's my eldest son (29) i'm rushing towards him fists up making him step backwards to a point where he falls back on the bed. by now i'd realised who it is and moved away. he takes great offence and storms off. i'm not sure if we are still talking!

a bit of background. i'm a 61 year old man living in a flat with my middle son (28). often my eldest son pops in on his way to work. he has a history of startling me with this sort of behaviour and i have asked him to shout out a "hello" whenever he lets himself in.  why do i feel like i'm the bad guy?
