The most obvious signals that a girl is ready for a kiss ...

Certainly non-verbal. No girl will directly ask you for a kiss. Yes, there are such situations, but this is rather an exception. But in other situations, you need to follow the gestures, facial expressions and behavior of the girl. For example: - the girl does not prevent you from being in close proximity to her (in the zone of personal comfort - a distance of up to 0.5 meters); - when talking, she looks at your lips and eyes; - does not move away when touched and touches you; - touches himself, plays with curls, bites his lips. It's time to act!
