I am so sorry that your feelings were hurt. Personally I think it is lovely and very patriotic. Sometimes recipients (family, friends, etc.) do not know how to accept a gift handmade from the heart. Unsure if they are embarrassed or just uncomfortable being receivers. I don't know what was going through his mind.....but then, I really do not understand my father either.
Again....I am sorry that your feelings were hurt and he was insensitive to your gift. Hugs from me to you.
