Not sure if this is the place to go but I'm trying to figure out what this man is saying in this footage.

He stopped my daughter in Kroger a few weeks ago and asked her if she wanted a puppy as if I wasn't even there. Didn't even look at me. "You can have one if mommy says you can." Then tells me he has a litter of chihuahua puppies. So persistent that we get one. We saw him and another guy all throughout the store until we left. I stayed on high- alert the entire time. Now, tonight I get a knock at my door and immediately felt a gut punch. The same man. He said he was looking for a guy with a cane but wasn't sure which apartment he was in. Referring to my neighbor who I just learned he randomly stopped while he was walking with his caregiver at some point, across the street from our complex. He didn't even use his name, just "the guy with a cane." Like a complete stranger. He has NEVER been over there or in our building before tonight. I feel with certainty that this is more than a random coincidence and it's not sitting well with me at all. I really really have the worst feeling about him. I've filed a police report already but my anxiety won't let me sleep. Watching this over and over. I feel like before he knocks he says, "where are you?" Maybe? 

I need some help!
