familiar with-familiar to

When you say that you are familiar with a subject, you are implying that you know about
it; you have, in fact, a good knowledge of it. When you become ‘familiar with someone', you
behave in a rather informal way with an individual: you become more friendly than is acceptable,
and in the process you do not give the respect that the person deserves.
