Rules of engagement Part 2

On a slightly different note: it is permissible to fall in lust with your partner’s friends, even if you’re still in love, and living with, your partner. It is even permissible to flirt with them, although it is not advisable to do so when your partner is actually there in teh room with you. It is not permissible, though, to gently place your hand on the friend’s knee at a dinner party, even if your partner is out of the room. Nor is it particularly well-behaved to then let that hand slide along her thigh until it touches the hem of her skirt even if you’re drunk and even if the friend does nothing to stop you, but we all make mistakes and if it stops at that then there’s no real harm done - is there?

 i typed 'hand under skirt' into Google images and this was one of the pictures that popped up. If anyone can explain teh connection I'd love to hear from them.
