A small thing my husband does that melts my heart: He loves watching videos after a long day, and he tends to have the volume pretty loud. But the moment I go to sit beside him and grab my Kindle/book, he turns the volume down to not distract me (ADHD anyone?). Or if I have some soft background noise going, he tries to grab his earbuds to not disturb me. It's so small, but it means so much.
