<prompt> Human: Im 18 for referenceI recently went to visit my grandparents a half hour away and while we were sitting and talking, my grandma slipped me a piece of paper and said While youre here, I want you to write down your social security number.I trust my grandparents, of course, so I figure this is for something important. However, I have no idea exactly what its for and I didnt ask because that might have been a bit nosy.So, what are the implications of me having given them my SSN?  <response>: Nosy? Lol its your SSN. Ask all the questions you want to.
