true. it actually saved the life of my desi tenant. she went to the 2nd storey balcony of my sillycon valley home and accidentally locked herself out as sliding door to balcony was faulty and could latch on the inside if slammed too hard. that was exactly what happened. she slammed the door from balcony to keep cool air inside intact as it was 93f outside. couldn’t get in, couldn’t climb, couldn’t jump. her iphone was inside. but, luckily for her, she wore her apple watch! she called me from the balcony, and i was able to find a spare key to get into the home to unlock the sliding door. it took a couple of hours but she was being baked under the hot afternoon sun. told her to break the glass door with a rod in storage room at balcony during an emergency but she was too dizzy to think straight. anyway she saved my door, and i saved her. otherwise she would die there from heat stroke, and nobody would know until her parents tried to reach her from india. i have to conduct welfare checks on her after that, but nobody conducts welfare checks on me. damn!
