I have many experiences with the word dear'
when I call it for most of the girl they deny to call dear and many accept it
I don't know what's wrong with it?
maybe I am stupid
so, please intelligent people tell me the truth behind it
It's an old word and not really used unless you're an old person.
e.g., it's a sweet word that your grandpa would use when speaking to your grandma.
And of course, you use it when addressing a letter e.g., Dear Sir/Madame . . .
