A true friend is forever! There is an old saying "Any time. Any place. Any where.". That pretty much sums it up.
A real dollar out of a fake billion of them. You only find one true.
Priceless...unless that friend is me. (See the last name. Dumb joke, but couldn't resist)
A four-legged one as a dog is a girl's best friend - loyal, faithful, companionable and has unconditional love.
