I wouldn't dare. My cat is very jealous of me talking to girls and her nails are very sharp.
My cat was extremely jealous too!
She was very antisocial whenever there was a girl at home with me.
Antisocial in this case meant following people in menacing way, sit on my bed and scratch to blood whoever dared to get close to it (apart me obviously, and that's gave a false sense of security to other people).
about the sitting on the laptop: that's normal behaviour.
cats seems to love being at the center of your attention, whenever you focus on something else then them.
It's not about food, it's really about attention.
My cat used to lay on the keyboard or on top of the monitor (CRT times).
Rubbing their neck/cheeks on objects (or people) is a way to mark them with smell: marking property.
