I don't remember on which forum I discussed July 4th (it was on a Friday this year), but I thought I would share what I heard today. During his homily, Bishop Dolan mentioned that the abstinence from meat has been traditionally dispensed for the Friday after Thanksgiving.
I was glad to hear this because I was all set to abstain. In my family, we celebrate Thanksgiving on Friday so certain members of the family can share Thanksgiving Day with their in-laws, girlfriends, etc.
