Inspired by the thread in Chat about boring things that made your life easier - what small things have you found made your romantic/platonic/family relationships stronger?
I once read that instead of apologising to people when you feel like you're being a burden you should thank them for being patient and supportive. It turns the focus of the conversation into a positive one and means they feel appreciated rather than further obligated to try and reassure you. So easy to do (and in retrospect quite obvious!) and it's improved some of my friendships immeasurably.
