One last post tonight. Linda and I started to leave the apartment this afternoon to go shopping. When we tried to open the door the lock would not work. We were in effect and actually locked in our apartment. These are the offending elements of our door. If I were a real McGiver type I'd have freed us in a matter of minutes (or seconds) by slipping a piece of plastic into the lock and sliding it back. I am not McGiver. Thankfully, Linda had her wits completely about her and called our faculty liason and got her to get in touch with the dorm mothers (we did not have their phone number so we could have been emailing you to call 911 in Tianjin to get someone to help us) so they could come and free us. This whole process took about 20 minutes because no one was answering the phone downstairs for "a long time". At least the key worked from the other side. I'm only slightly paranoid every time I close our door now.
