<human>: Can you summarize the given text in a few sentences?

So this just happened. Thank god I had to change my bus (I'll get to that in a minute). I should start by telling that because I don't nearly get enough sleep on a day, I usually sleep on the bus to home after work. Bus ride lasts about 45 minutes, so good moment to go for a quick nap. I've been using my iPhone to wake me up in time so I won't miss the bus stop where I gotta change bus. I've been doing that for over a year now, on a pretty crowded bus.

Today at one of the first stops a woman gets on with a crying baby. When it's Friday 6PM and everybody wants to get home and is tired nobody wants to hear a crying baby. After about 5 minutes or so people were getting agitated (you could tell on their faces). A little while later the baby shuts up and I fall asleep. That's where my TIFU happens. I've always used my annoying iPhone alarm to wake up. I NEVER KNEW THAT EVERYBODY ON THE BUS COULD HEAR THIS AS WELL. I've always thought that I was the only one to hear it because I always put in my earphones. Apparently, EVERYONE can hear it and nobody ever bothered to tell me. So my alarm goes, I wake up and with me that baby starts crying again. Then I had the whole bus looking at me, judging because I made that baby wake up again. Lots of angry faces. Thank god I had to change from bus soon after..
<bot>: woke up a baby with my iPhone alarm that apparently everyone can hear and the baby started crying, making a lot of people angry at me.
