A staff submission to the virtual memory wall. What would yours look like? (Mark Luckie/The Washington Post)

The Sept. 11 attacks took place over the course of a few minutes in the morning hours of an average late summer Tuesday. Within minutes America changed. Our individual lives changed, too.

It means that every trip to the airport means the shoes come off and we vaguely feel like we’ve already done something wrong as we wait in the long security lines. It means that when the office floor starts shaking, a terrorist act is higher up on our list of fleeting thoughts than an earthquake. And it means that people still living and working in the Pentagon were there that day in 2001 that a jet crashed into their office.

We want to hear how life has changed for you. We’ve offered ways for you to contribute online, but BlogPost’s Melissa Bell and I want to talk to you in person. We’ll be hosting a Coffeehouse Newsroom Tweetup Wednesday, Sept. 7, from 9 a.m. to 6 p.m. The good people of The Washington Post’s go-to Caribou Coffee are letting us hang out all day, and we’re hoping you’ll stop by. Come tell us how 9/11 changed your life, create some social art for our Virtual Memory Wall, or just stop by and say hello. Here’s what we’ll be asking:

How do you feel when you think about Sept. 11 today ?

We hope you’ll come and show us, as well as tell us.
