<human>: So this morning i was taking my girlfriends dog( its a 4 pound Pomeranian poodle mix) its cold so I figured screw it ill take her out in my pajamas (long sleeves/pants). When I go out I can either make a left/right and I look to see if there's another dog in a certain direction so I go the opposite way. I look to the left and see this old fuck a with a dog so I go right. 

I walk my dog to the end of the sidewalk(without a leash because she stays by me). she can fit through this fence onto another un-occupied lot(fence sort of looks like jail bars hence why she can fit through it)...I like this because I don't have to pick up her poo. Anyway old fuck apparently followed me and I hear "SO ARE YOU GOING TO PICK UP THE SHIT" i turn around and see the old fucker and I say no. He says I better pick up the poo or hes going to report me for having a dog without a leash to the cops by taking my picture and report me for leaving poo to the apartment complex I live at as well. He proceeds to take his phone out and I think fuck it ill just pick up the poo.

So I grab a bag(theres dog poo bag stations near by) hop the fence and pic up the poo. I turn around and the fucker is trying to take my picture. So I put my hands in front of my face and rush to block the camera. Fucker steps back and whips out a massive knife. Some words are exchanged and I call him a bitch for whipping out a knife on someone in their pajamas and hes like fine puts it away and then challenges me to a fight . I didn't hop the fence to fight him because he had a knife/plus this would be the dumbest I went to jail story ever but now I feel like a bitch......Guy was like 50 easily 1 1/2 times my size and covered in tatts looked like some old biker dude. Would you guys have fought him?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Some guy whipped out a knife because I didnt want to pick up my dogs poo...now I feel like a bitch because I didnt fight him.
