star-crossed lovers or potential dinner?

We have a new neighbor.  We don't know much about him.  He is orange, has 4 paws, and spends a lot of time peering over our patio wall...

In the evenings, when we open up the patio doors for a breeze, we have started to notice Lola heading outside.  She sits patiently and stares up at the neighboring patio wall.  Just around dinner time this is what we see...

It is a short exchange, perhaps 15 minutes total.  Then someone will inevitably be called back inside and the encounter comes to an end.  At which point Lola attempts a closer vantage point!  Not sure if this gesture is unrequited love or more epicurean in nature...
