Input: Text: as i'm writing this i'm now in a bus on my way towards my hometown as my mom asked me to go back this weekends. so as the title reads, today i fucked up for accidentally leaving my apartment key inside and locked myself outside my apartment. 

i woke up today at 2:40 pm (had a dota 2 marathon last night) and after brushing my teeth, washing my face and all that i decided to go get some food first before getting my shower. so i grabbed my wallet, searched for my phone that got lost somewhere on my bed and after i found it i went out straight away leaving the most important thing behind, my keys. now, all my friends are not home, its holiday and its just me, since i forgot to buy the bus ticket earlier so i am the last one who left the house. the funny part when i think about what happened is this. as soon as i locked the door and shut it off, i realized that its too late, i realized that i left my keys inside! i wish i could see my face at the very moment i realize that i fucked up. 

my bus is tonight at 10 and i still had 7 hours to 10pm. what did i do? i grabbed my lunch and after i finished i went and buy pliers to try to disassemble the door. i was so stupid for trying that. i know. but i was desperate. i shouldn't have done that though, i wasn't able to disassemble shit anyway. it was for nothing. and now i am not even sure that any key would unlock that door anymore. thats my second tifu.  

sure, i could always get in through the window, but i hate risking falling off from 17th level to ground level just to get inside my house, i hate to die for just trying to get into my rented apartment.

and here i am. on the bus, without bringing other clothes aside what i'm wearing right now, i left my laptop, my clothes, my keys inside, smell like shit for not taking any shower since yesterday, and whats worse is i'm not even sure how would my housemates get inside the apartment when they get back. not to mention that i need to pay for a new door knob. tifu, real bad. =(

TIFU by forgetting to bring my apartment key with me!
