You've got a friend in me

Sittin' and knittin' at the local yarn shop with an owner thereof, I spent a couple quality hours today.  She is fabulous, folks. Kind, considerate, fair and full of smiles.  I watched as she viewed to vintage purses (the shop is a vintage shop too) a fellow brought in to sell.
"What do you know about the Chanel bag?" She asked him.
"I know it was my mom's." He replied, "That's all I know."
She bought some of his others then referred him on the shops that could give him a better price for some of the name brand bags.
"Anything I offered you would be under their value, I don't want to pay you less than you could get elsewhere."
Such a sense of fairness.
I really enjoyed talking with her as we knit.  I spend much of my time alone, so having a friend to pass time with was a great boon.  I consider her a friend.  I have been slow to accumulate actual friends here.  I have a smattering of acquaintances, sure, but a true friend.
I guess I am fastidious about the distinction.
Consider the term, friend.  In some contexts it has a very broad application - any one with whom one shares a positive regard.  To me the preceding meaning is more accurately "friendly".  I consider folks who meet that basic criteria as friendly acquaintances.  I may know their name and a weensy bit about them.  I may share a brief interaction around a common purpose (playing board games or bridge for example).
A friend, however, is much more.  Friendship requires more.  More trust, more familiarity, more than a focused pass time, more of the self given in the exchange.
So, two years into the interaction, after many a Saturday at knitting group, after stories shared and goals revealed, after learning about personal history and people in each others lives, I consider some of the knitting women more than acquaintances and a fair few actual friends.
