1. Always walk her to her door.
2. If she is being stubborn and refuses to make eye contact, she does not want to kiss.
3. She will look gaze into your eyes and lips will be parted, showing her hunger for your lips.
4. Be the man and make the move before she gets bored. Women want a man to take the lead.
Good luck guys and I hope this helps with handleing the goodnight kiss!
