Trustworthy

My father is a professor, he wears glasses and his build is quite impressive. Every time we went for a family vacation, he could be sure that somebody would ask him for directions at the most peculiar places. An old Italian woman would ask him where to find some tiny street in a small Italian village. Carrying a camera and a map, he would still be asked for a location of a local city council in Vienna. Well, why am I writing this... Even though I look like a 100% guiri (not from a concentrate, but wearing shorts), three families stopped me on the street today to ask me for directions. It runs in a family I am afraid.
