The air-raid (a protection attributed to a guardian angel)

During WWII during an air raid in Croatia, a mother quickly grabbed her baby and placed him into the pram.  She wanted to get to the air-raid shelter as quickly as she could, however outside the snow was very thick and the pram could not be pushed along.  During this stressful time a man appeared and told her that all would be well.  He then disappeared.  All the difficulties immediately dissolved and she was able to push the stroller along and safely arrive at the air-raid shelter.  She believes that the man who appeared is her guardian angel.
