gold and silver

I new here in town, and also semi-new in accumulating G & S. I'm looking to buy some more, but not sure of the timing, even though I realize these to precious guys don't need a clock to tell them they're the real deal. Is there a particular report coming out tomorrow that could influence the price of these, and does anyone think these could drop lower before the grand trajectory? Also, does anyone have any advice that I could share with my Wife on why it makes sense to buy more gold and silver, when she emails me reports showing how especially gold has been such a bad performer for such a long time (and I didn't know it could sing)
