kapusta, like ames says, with a fork and knife ONLY. I’m very proper when it comes to these things!
Yossi, I believe it is a myth that they will cause your fingers to shake when you get old. I was discussing it with someone recently and she was freaking out (that I crack my knuckles). She kept on saying ‘what, you’re gonna do it on a date? what’s the boy gonna think?’ blah blah blah. I finally realized how really unclassy it looks (and sounds) so I decided to stop. It was really hard in the beginning but now, I’m so used to it. I’m so happy I stopped!
