What does it mean when a stranger calls you "Friend"?

Sometimes, we get emails:

Dear Friend.

I am a Financial consultant, my client have One Billion euros for RENTING depending on any amount your capacity can carry or Did you need a soft-loan to finance your business or project? kindly mail me through my email account(xxxxxxx@xxxxx.xxx) for more information, if you are interested.

Best regards,

XXX XXXXXX.

And sometimes, we write back:

Dear XXX,

You wrote just in time! Best that you immediately halt exploring any other prospects for your client's capital, because nothing can match the opportunity we offer you to come in on the ground floor by investing all one billion Euros with our global re-launch of the NeuroCooking brand.

Capitalizing upon the recent explosive growth in page-views achieved from Kensington & Hoboken, NeuroCooking, with its proven business model, is now prepared to go global.

Your seed capital will bear great fruit! Send a check, quick. We promise to take good care with it.

Best regards,

JP
