If your neighbors block the steps habitually...

No steps to get into our house

thankfully we don't share stairs we have separate houses

You could always wear hard heeled shoes and step on their fingers as you step around them.
I did this to someone by accident and they didn't loiter on the steps anymore.
The stairwell was too narrow to get by and they weren't moving so I had to scooch around them. Whoops!

Years ago a horrible man moved into the flat above me with a rottweiler. He used the pretty little communal front garden to exercise the dog in. The dog ruined it and left poo everywhere. When we asked him to take the dog for a walk he became very abusive and sat in the doorway with this threatening dog. I had a back door so used that to avoid him, but sadly an elderly neighbour was attacked and died a few weeks later. Nothing was done about him

Push 'em off.

I assume this is in the hood? Seems like typical behavior, they might be talking about what they want to study at Harvard.
