Driveway Drama with Neighbor's Entitlement

Okay so this is a bit long but I need to get it off my chest. I live in a small

cul-de-sac, nothing fancy, just your average neighborhood. My driveway fits

two cars, mine plus my husband's, perfectly fine. For the most part everyone here minds

their own business. Except my neighbor, let's just call him Jack. For whatever reason,

he thinks my driveway is like extra parking for his family and friends. First time it happened

I thought it was a mistake. His brother's car was in there, he said it'd just

be a sec. A week later it was some friend of his dropping something off.

I didn't love it, but I figured whatever, not worth making it awkward. But it kept happening.
