Why?

Was rudely woken by the dog at 530am, & then tried to go back to sleep.
Couldn't . Got up and was in kitchen way too early to start feeding mother.
Then I heard the racket up stairs, checked CCTV from kitchen & saw police, lots.
Went up & met with the night porter & assistant manager, who looked awful.
When I asked what was up,was informed "a jumper". Looked out into the dark, police tape, scenes from CSI on the doorstep.
Then a young pc came in & asked if my sister could come in! She'd seen the ambulance/ police then thought mother!
Told her,and the boys in blue came to speak the the boys. Told them just to get on with te interviews & we'd organize etc, I mean we ran the place forever.
Transpires the guest had come own at 5.30 asked for a drink, changed his mind & within 10 mins had smashed the window in his bathroom( windows can only open 10cms) & squeezed his body out onto the ledge & swan dived down 5 stories, maybe hitting the railings ( small mercy he'd not impaled himself) hitting the umbrella & table in he basement & onto he stone. He was alive but not for long. I just hope he was too far out of it to be in any pain.
Police came etc, tent up & the rubber nickers in street& on the buses.
I'd only seen him twice, ironically my sister who rarely visits had been in 3 times & had lengthy conversations with him.
He was a heavy drinker seemingly & a troubled soul.
Of course in times of crisis I went into calm logical mode. Which I think some thought cold hearted, but it's me, don't why, but I don't do hysterical for serious stuff.
We did decide that when we ran te place we knew our guests, if long term or regulars we knew them& their moods & did wonder because they new regiment of young staff with little care about being friendly with any guest, missed a trick.
Though he'd written a note,planned it& was pretty determined to end hs life, would the fact someone knew a mood change be able to do something to stop it? Or would it just delay?
I know some folk think ( me included ) that suicide is a selfish act,but, I do think you have to be desperate and very brave to carry it through.
Depression is a shitty illness ,since the stroke I've suffered from it, though I know when I slip into it. But, I don't know even in my darkest hour I could end my life. I'm too big a coward. Police didn't tell us what his motives where. But wherever he is now, I hope his troubled mind is calm & he's free from any anguish.
