<human>: Okay, so this was yesterday morning. 
I sleep at my dad's place once a week, and that happened to be the night before last. 
I get up the next morning, have a shower and get ready for school, as I leave the bathroom I see some old guy I'd never met before, just standing inside my house. About 6 feet past the front door, with no one insight, I immediately assume no one had let him in. So I start to question him. It went a little something like this, 
Me: "Hey..." 
Him: "Hi, how's it going?" 
Me: "Yeah I'm good..."
Him: "I'm here to fix the car" (Now, I had no fucking clue my dad's gf's car was fucked) 
Me: "What? The white one?" 
Him: "Yeah, have you got the keys?" 
Me: "No, mate. I'm also pretty sure the car's fine..." (Now I could tell he knew I was confused as all shit right now)
Him: "Are you sure? This is X's house, right?" (X is the name of my dad's gf mother, but I never made the connection. And she doesn't live with us.)
Me: "Nah, it isn't." 
So the dude left, walked out the front door again. While I'm feeling weirded out to shit because I don't know what the fuck just went down... 
After all that, I went to make breakfast and not long later dad's gf came to the kitchen, I told her about the ordeal and she told me it was actually her like grandad or father in law or something. So he was actually just old and confused. He had mixed up the names of my dad's gf and X, as well as the reason he was there. The car was broken, but he wasn't there to fix it, he was there to drive us to our designated places (work, school, etc.)

Give me a shortened version of the text
<bot>: Old guy I didn't know came to my house, I kicked him out because he said he was looking for some woman I didn't know and a car to fix, turns out he was my ride.
