The SUV selling drugs- it must have moved because I can't find it.
Don't get a roof deck- Don't bother with a roof deck unless you are a big apartment building or if it is right off of a kitchen. Roof access yes, roof deck no. Why? I have observed about three houses/condos that face New Jersey Ave that all have roof decks. Nobody hangs out on them, not for any length of time. I have heard the odd party (can't help to hear them) go up on the roof and then in less than an hour make their way back into the house. If you really want a roof deck, interview homeowners of similar houses and ask them about use and maintenance. Decks adjacent to the kitchen are a different story. Roof access, on the other hand, will make you popular with your neighbors if you're part of a big rowhouse row. Your neighbors will await your arrival home so they may ask if they can use your access to get up on the roof to deal with their HVAC unit or Dish or figure out that leak in their ceiling.
Support Local Non-profits- Think of all the non-profits that enrich your life, WAMU, WPFW, maybe performances at the Kennedy Center, the Fringe Festival or the Woolly Mammoth, art at the Phillips or the Artomatic, advocacy groups like the Washington Bicyclist Association or Casey Trees. You can also help people who help people who are worse off or trying to improve their lives by donating to Bread for the City or N Street Village.
Save for Retirement- I and the Help we both plan to die at our desks, but we still throw money at our retirements because you never know when your employer may take you out to lunch and change all the locks and passcodes while you're out. <-- This is based on something that happened to the Help's old supervisor.
Don't leave knives out on the street- That kitchen knife you put in the 'free' box on the sidewalk could kill someone. If you see a knife take it, you might save someone.
Be aware of your surroundings- Look up from your iphone, scan the sidewalk in front of you for dog poop, loose bricks, teenagers, cyclists, neighbors who might want to say 'hello' and drug dealers. Pick a playlist and put the damned thing back in your pocket. The closer you get to home, be more apt to interacting with the surroundings.
Citizen Policing- There is an unwritten law in DC, it is seared in the hearts of almost all the residents, 'stand on the right, walk on the left.' The authorities ignore this law but it is enforced, strongly and regularly by everyday citizens. I do it, my co-worker does it and I see others do it as I descend into the Metro system. We tell complete strangers who are mindlessly standing on the left to move over. Some do it gently, others scream a litany of profanities and insults, we all have our own style. When I see people enforcing this rule, I am reminded of Cambridge. Cambridge, England. I and a bunch of us from the Univ of Florida (Go Gators!) were studying there for 6 weeks. One of our party, Bill, rented a bicycle, and violated the rule of riding on the sidewalk. An old man walking on the sidewalk hit Bill viciously with a rolled up newspaper and told him to get the hell off the sidewalk. Thereafter, Bill stayed off the sidewalks of Cambridge. Imagine DC if certain rules were enforced by armies of seniors with newspapers.
Don't argue with crazy.
Read books- Cookbooks, reference books, the odd romance maybe (those things are mental junk food), audiobooks, a classic here or there, a history, something bigger than an article that will engage your mind if not your whole self.
Concentrate on your own happy. For me it's being right here, in this city, in this neighborhood with you. That and a really good cup of tea.
