8 of my neighbours constantly have their apartment doors open - sometimes a bit, sometimes a lot, but constantly and every day. i'm thinking of reasons why...

• nobody lives in there (proven wrong, i saw people walking in and out)
• to get more fresh air (but the windows beside the doors aren't open??)
• so the post delivery can put their packages inside?
• the locks are broken?
• they have pets that are allowed to go outside?

SOLVED IT! there's another hallway behind those doors! they aren't apartment doors!
