Weird ass neighbors

We have neighbors that won’t even glance at us. I just left the house to go to work and on my way out, two of the neighbors; grandma & a grandson, were outside right in front of my door. I knocked on the door so they’d see me trying to come out. The grandma looked back at me, grabbed the child, went inside and locked the door.. And I was ganna say goodmorning to her 😂 Another time, some old man was out there at the same time I was going to work, I said Goodmorning to him and he completely ignored me. I told my fiancé and he said that that is how they are, that they have always ignored my fiancés family. And just yesterday, they were outside again and I went downstairs for my food delivery. The minute they saw me come out, they all ran inside… ok 😂 super weird but ok.
