TIFU by not realising my computer's alarm was going off throughout the entire duration of a 1hr flight.

Having an early flight to catch this morning, I set three alarms on my devices so that I'd get up and definitely not miss it. Unknowingly, my alarm on my phone synced to my computer. Fast forward to getting on the plane no hassle after all 3 alarms went off successfully, earphones in and music playing. It was before the plane was taking off that I realised some idiot's alarm was going off in what I assumed was in the overhead luggage compartments. No worries, no one else seemed concerned I'll just bump up the volume of my music and someone will do something about it eventually. 1 hour later, that bloody idiot's alarm is still going off. I had stowed my laptop in the pocket in front of me (didn't use it during the flight) and upon putting it back into my bag I realised it was quiet warm. Odd I thought but I shrugged it off. Finally, in the car home and I notice that the exact same alarm is still going off. It was at this point I thought I was going slightly crazy until I leaned closer to my backpack to hear the chiming resonating from my laptop sleeve. Yep, I was that bloody idiot who ignored the sounds of an alarm and instead turned up the volume of my music for a 1 hour flight. Cheers Windows 10.

TL;DR Alarm synced to laptop, didn't turn off alarm on laptop, it played throughout the duration of a 1 hour flight right in front of me while I listened to really loud music.
