Be a good human. Hug everyone you love just a little more tightly. Be present. Say I love you way too much. Never leave someone in an argument. Swallow your pride, and try to resolve quickly. Be the bigger person, apologize, and then listen when they are hurting. Take a lot of pictures with the ones you love, they are your only physical reminders of times well spent. You never know when it will be the last time you see them, so please don't ever take any minute you have for granted.
