Confronting limitations has been the theme lately. Just last night, I was to drive to the in-laws pre-Christmas gathering after work and join my family there. They had left earlier in another car. But not long after I got home, Dorothea called me from the cellphone, and said that I should wait until the morning to go. It was dark and raining. The headlights and the glare would not have been pleasant for me. True enough.
