<human>: Give me a shortened version of the text

This happened like 10 minutes ago so sorry if its not 100% coherent I'm still really embarrassed about it. 

I was coming home from college classes, and since my car is currently getting work done my grandmother had to give me a ride home. Well, once we pull into my neighborhood we notice a rather large golden retriever just walking around. I ask my gram to pull over so I can call to what I thought was my best friends old dog (she moved away but it still lives at her parents house) now note: This dog responded to Sadie, my best friends dogs name. Now, I call it over and let it hop in the car, another guy in my neighborhood who I used to date in highschool comes running down the hill. My gram then proceeds to continue driving past this guy while he just looks at the car in total defeat. After about 20 feet I get my gram to stop, hop out the car and go "uh....this is your dog isn't it?" And he only responded with a salty af "yep. He got loose."

Turns out he also has a golden retriever that I didn't know about and it ran away.
