Using titles such as Mr., Mrs., Miss, Dr., etc. demonstrates respect. In previous generations, it was a social necessity and simply good manners. One would consider you rude and uncultured if you were so presumptuous as to go straight to a “first name basis.” First names can imply an intimacy that does not exist and it may offend a new person until they know you better. Be wary of making assumptions.
