We were visiting the Washington memorial back in 1964 on a family vacation. My mother, who was extremely overweight, was wearing a somewhat formal black dress, as many ladies wore in such dignified places back then. She had already been complaining about being out of breath that morning since we had already done so much walking. But as my sister and me kept begging her to walk up to the top with us, some young girl about 9 or so came out of the crowd, grabbed my mother's hand and begged her not to go inside. She then ran off into the crowd.
This scared my mother so much, that she sat down on a bench to gather her wits. Needless to say, she didn't leave that bench until we headed back to the hotel. Mother has always speculated that this was her guardian angel. It sure was a strange thing though.
Heb 13:2 Be not forgetful to entertain strangers: for thereby some have entertained angels unawares.
