Last night we had friends over for dinner and playtime. After dinner we were all in the hot tub for a bit and my playmate and I got out to head inside for more play, leaving wife and her playmate in the hot tub. Mindlessly I locked the sliding door when we went in. Later after we were done playing we were commenting that my and wife and her husband had not come in yet. Then we heard a noise downstairs. At first I though it was them opening the door, but it was them banging on the glass, hehe. They were just at the door for a minute or two but I'm sure if felt like hours as it was very cold and windy out. Oops
