TACTIC: Bigger than Yours
Find a heritage site about which unsupported assertions are made, be they unfeasibly grand:
“D------ - the only nation in the world where you had people risking their own lives in order to save the Jewish population.”unlikely:
“M------- is perhaps the only British town with a historical family connection to the development of the Japanese shipping trade."
or unnecessarily modest:
“S-------- may justly lay claim to the title of being one of the prettiest small towns in Dorset.”
and make your own unsubstantiated assertions about it.
