I feel that way every time I talk with my dad on the phone. He lives in another state and it would be hard for me to go visit. Even if I did go visit the state of his health would probably shock and sadden me as he's not always with it over the phone and he has a number of health problems. Whenever we get off the phone, I always act as if this could be our last conversation and most of the time I tell him I love him as we are getting off the phone.
