definitely shake hands. just be enthusiastic and at least pretend like you are excited ot meet them. theyre going to make small talk just because there's nothing to really talk about, so just answer questions enthusiasticly. and dress conservatively. can't go flaunting yourself in front of his family lol
When you're shaking hands with a man, for God's sake, don't do a limp fish shake. Firmly, but not harshly, shake the guy's hand while looking him in the eye. Only takes two seconds. But done wrongly, and you can earn instant dislike. I've shaken hands with girls and instantly thought less of them because it felt like I was shaking a dead fish.
You guys have a date tonight...I'm surprised he's not watching the wild card games, Green Bay and Minnesota as well as right now Houston and Cincinnati (me being an Ohioan I want Cin. to clober Houston, even though I have family in Texas)
Wear some good clothes. I don't know about hand shakes from a girlfriend to a boyfriend's family, but if they offer their hand just make it a firm handshake.. And don't be fake just be the nicest you. No one likes fake people. Anyways good luck
