<human>: Can you succinctly summarize the text in 1-3 sentences?

Throwaway time because a few friends know my reddit account.

I am a 17 year old dude, currently living with my mother and step father. I came in from playing basketball in the hot weather outside (it was about 90 degrees fareinheigt, played for an hour) and was really thirsty. I am very eager to replenish my system with fluids. I start loading ice into my cup, and I pull my cup away to early, and some ice falls on the floor. Me, being the lazy fucker I am, I pushed it under the fridge, got my water and went on with my life. About 20 minutes later I went to go work out, and I come home about 2 hours after that. I look to my right when I come in from my garage and I see my stepdad on the ground in front of the fridge, knocked out, bleeding from his head. And his clothes were wet.  I *flip* out and I mean flip to max, that I scream and go black for a few seconds (at least I think). He is in critical condition and is on ICU. I am currently in the lobby of the hospital, and I don't know what to do. Do I confess it was my fault? What do I do if I get a chance to see him??? Fuck.
<bot>: I kicked some ice under the fridge because I am a lazy fuck, and my stepdad tripped on it and cracked his head. He is in intensive care.
