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

So this happened a few weeks ago but sittin here waiting for the bus reminds me. So here's my FU. 
On this morning I wake n bake before class so I'm at a good [7]. At the bus stop I wait at two differs routes pass by. One goes straight the other turns the corner and goes the opposite way. I need the latter bus. Waiting for the bus with me today was an older gentlemen with one of those 4 legged walkers. We make small talk and turns out he is waiting for the same bus. 
A few minutes go by and I see our bus coming. Great a couple minutes early I think as we board, both the old man and myself. Then the bus passes the turn on my street and it hits me that in my high state I got on the wrong bus! I immediately get off and sprint to the adjacent stop where the bus I need is already stopped picking people up, it was right behind this bus apparently. I sprint full speed and make it. Adrenalin pumping and quite stoney I sit down. Then I realize.. after we pull away that the old man was still on the wrong bus.. I look back and he had gotten off and was trying to make it but we had already pulled away. So I just fucked over this old man making him miss his bus. I feel like a such an asshole just thinking about it.
<bot>: got high and directed me and a handicapped elderly man on the wrong bus. I was able to run and catch the right bus but forgot about the old man.
