Input: Text: i work as a software developer for a company whose offices resemble an old, large town house, both inside and out. about 6pm everyday we have some cleaners who come round clean up and then lock up for the night once everyone has gone home. i normally work late monday to thursday so i can get work done without the distractions of people asking you things every 10 mins as well as leave early on friday, but i always left by 7pm so i'm out before the cleaners need to lock up. 

as i work on the top floor i have an arrangement with our regular cleaner where i'll turn the lights off on the stairs before i leave so she knows i've gone and doesn't have to walk up stairs to see if i'm still in. this is where the fuck up begins ...

it's about 18:50 and i start shutting down for the night... close the window, turn the radiator on for the following morning etc. i grab my bag and open the door to the landing. shit me was it dark... like pitch black, couldn't see a thing. i managed to fumble around and find the light switch for the stairwell and headed downstairs without thinking too much of it.

that was until i get to the door... i pulled on the handle and, well, nothing happened. shit! so at this point i start freaking out a bit thinking i've been locked in and i can't get home. i started banging on the door hoping the cleaners would be outside still and might hear me... 10 mins of banging on the door and shouting later it doesn't look like i'm getting out.

this fuck up continued when i came up with my escape plan... being an old house, some of the ground floor offices have massive sash windows that even i could fit through. so i walked into the office and proceeded to open the window. what i failed to notice was that we have magnetic alarms on all the windows... so when i lifted the window the burglar alarm went off.... this literally couldn't get any worse. i decided my best approach would be to close the window behind me and run home, so i'd be off the premises by the time anyone noticed. 

all good... nothing to worry about and the alarm would be thought of as a false alarm...but after a couple of minutes i realised i'd left my keys on my desk upstairs.... i thought it would be at least 15 mins before someone turned up to check out what set off the alarm so i could quickly get back grab my keys and get out before anyone turned up...

well it turns out i was wrong.... i'd made it back downstairs having collected my keys and climbed out the window... just as i was shutting the window behind me.... boom!... i'm tackled to the ground by a policeman... fuck! 

turns out our burglar alarms have a direct response line to the police who respond within 10 minutes should they go off. i spent the next 15 mins in the back of a police van and a further hour in police custody until i could get my boss to come down and vouch for me not being an intruder.... fortunately my boss is a cool guy and seemed more amused than pissed off.

i've just got home. 2.5 hours later than normal....fml
