Do you know any of your neighbors, get any newspapers delivered, work in your yard or on your car or anything? I run into my neighbors fairly often as I live in a townhouse and my group of houses is on a little circle so we can see 10-15 front doors easily.

See if you can stay connected with your immediate outside, your neighbors whom you know; make a little "circuit" of your yard or block and walk it during the day, picking up a rock or collecting trash in the street to throw away.

You don't have to talk to anyone, just "wave". But keeping in contact will make it a little easier when the holiday is over to get out again.

I'm good friends with my mailman too; often talk to him and when we drive through the development, he and I recognize one another from my car even if he isn't to our street yet. That makes me feel like I "know" the whole community since I'm friends with him and he's "everywhere" :-)
