Better to call and not need it, then need it and not call.

If it was happening again, the exact same way, would you call? No point in second guessing yourself. If everyone involved walks away, in one piece, and no one is seriously injured, then you handled it the right way.

It's nice to have a pleasant relationship with your neighbors but completely not necessary. Some times you have no choice what type of relationship you have with your neighbors. At times, their actions dictate the type of relationship you have.

Not that it is worth anything, but it sounds to me like you did the right thing. If you are concerned about this family, you could always put in some time, be friendly and see if there is anything you can do to make their life more stable. Not necessary, but it is an option. Just don't try it when there are any types of mind altering substances involved. That is like rolling a big rock up a very long steep hill, over and over and over...

Be safe.
