Need quick advice. Be a dick and tow someone or tow myself?

This is stupid a stupid post and OOT will basically decide in the next 20 min if I tow someone or risk getting myself towed. I live in a 4 apt building w/ 14 parking spots which are designated. I came back from a friends house and someone is in my spot and I took the very last spot in the lot that belongs to another resident. The other resident only parks here every other weekend or so as she isnt here often. The person in my spot is likely friends w/ the other residents (who I a barely know) who are having a party tonight. It is a busy area so it's likely the person in the spot is parking there for close access to bars/restaurants.

Anyway, if I leave my car where it is I risk the other resident coming back and having my car towed. If I gamble and tow the car in my spot I risk the person coming back being furious and potentially keying or damaging my car in some way. Our lot is already way overfilled w/ people parking in spots against the building. I'm slightly annoyed that I didn't get my spot but both risking my car getting towed and having my car damaged worry me more. So OOT, do I tow the bastard?
