Sender, try remembering that when you were a child, he had to slow down to accompany you. When you first learned to walk, he had to pace himself to your speed so you could keep up with him. I am sure he was late many a time because you held him back. I am sure he had to readjust his schedule to meet your needs. I am sure there were many times he had to cancel his appointments to accommodate your needs.
Sender, B”H you have a father to accommodate. I don’t know how old you are or how old he is, but life does not go on forever. Cherish every moment you have together. Cherish every extra second he holds you back and you get to spend with him. Believe me it is time well spent and not wasted.
