Obtaining money from anywhere but a banking institution can be a very uncomfortable situation. The fear is that someone will be taken advantage of - either the borrower or the lender.You were indeed lucky to meet someone who was a relative stranger that lent you money so quickly after making your acquaintance. I can only imagine how you must have felt asking and receiving the money.
You are indeed lucky to get the assistance when you really needed it. These unexpected act of kindness are a reminder that there are good people in the world.
