<human>: This happened yesterday, but since it ties into today I decided to post it.

As somebody who has never had the responsibility to feed someone's fish before, I realized that I am in fact an idiot. Today is my birthday and my mood is absolutely awful right now because I have committed homicide against an innocent fish and my friend's confidence.
Yesterday, I was goofing off at my friend's house. I asked her if I could feed her fish, because hey, that's something I've never really done before! So why not? She agrees, so idiot me decides to chuck a whole handful of the little edible fish balls into the fish bowl. Eat up, little fish, for your destiny is set; your stomach is gonna blow up. Yeah. I made the fish's stomach blow up. You're probably thinking it's just a fish. No. It gets worse. Not only did I cause the fish to become a bomb of edible fish balls and guts, I got my friend screamed at. Apparently her step dad called her irresponsible, selfish, and an idiot, because he thought she killed the fish. No, it was me. I am the fish murderer. My friend got blamed for being a fish terrorist when I am the villain here. Needless to say, my friend came to school crying because she got screamed at so hard. So TIFU by literally messing up the easiest task in the entire world; feeding a fish.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: over fed a fish, it blew up, got my friend yelled at because i don't know how to complete simple tasks
