My dad was our rock. Although he was diagnosed with multiple sclerosis in his early 30s, he was our provider, our champion, our hero. As he got sicker, it got harder for him to walk, it took him longer to get dressed in the morning. But if he was in pain, he never let on. He never stopped smiling and laughing — even while struggling to button his shirt, even while using two canes to get himself across the room to give my mom a kiss. He just woke up a little earlier and worked a little harder.
