Because it needs to be said.
Please, please tell your loved ones that you love them. Don't let a day go by without showing or telling them how much they mean together. You never know how much time you'll have, and it's too short to spend taking them for granted. Whatever you're fighting with them about, put it to the side at least long enough to let them know that you love them. Please don't let the people in your lives go about their daily lives thinking that you hate them. To some people, just a few words makes a huge difference.
