According to a
psychology study, most people who has a deficiency (eg certain part
of their body may be below normal size), would have a tendency to
deny such a fact by making a boastful claim to the contrary. A
short guy would try to claim he is tall. And they would normally do
it somewhere that would be difficult or impossible to disprove
their claim.
So, when someone
comes here with a claim like this, we ought to sympathize with
him.
