I have a short list of qualities that might mark you as someone from the 'burbs. In other words, this might show what community you belong to.
You might be from the suburbs if:
You have a garage but you can't get your car into it. (Now this could be because you have too much stuff stored there or your car is just too big).
You built either a shed or added on a new section to your house just to house your Christmas decorations.
Your most recent night-out was a parent/teacher conference.
Summer is sometimes called garage-sale season.
Of course you also know that you are in Erie because there are only two seasons: winter and construction season.
Your mortgage (or even your rent) could balance the national debt of a third-world country.
You jog five miles a day but spend 30 minutes waiting for a closer parking spot.
