My door doesn't leak light

I really like my Madeiran apartment :) It's got the best view out of all the places I lived at including the apartment I almost moved into in the Pacific Heights where I could technically see the Marina, but it was about 2 inches of Marina. Also, if you walk out onto the edge of the balcony theres a bit of ocean view too! If you look out over the balcony, you're greeted with banana trees!!! I love bananas, I'll be eating a lot of bananas this year. I also noticed that although the apartment is on the older side, its so well kept. The doors all fit perfectly and don't leak any light. I didn't know doors could actually do that. I feel like the doors in America are maybe made so that there is some space at the bottom at least. It's so strange living here after living in my sf apartment with what I like to call the crooked bathroom.. The door was crooked, the shower door was crooked and the door to the storage area beneath the bathroom sink was also crooked. Basically anything that had to close in the bathroom was crooked. And all that crookedness makes me appreciate my current well kept apartment so much more now :)
