Breaking the touch barrier is key. If you touch someone and they touch back, that"s a reasonable sign that they"re actually interested in you. Similarly, if they make an effort to get into contact with you. (You can test this at, for instance, a party by disengaging politely and talking to someone else and seeing if they reinitiate conversation.) Laughing at jokes, particularly ones that aren"t funny. Some girls have tells: for instance, when I"m attracted to someone I always play with my hair.

The classic list of IOIs to watch for, from the Mystery Method:

The old-school rule was generally if you get at least 3 of these from her, you can kiss her and she'll likely be receptive to it (or might giggle and turn away but still be into you so you can just stay un-phased and try again later in the pickup lol).

Stuff like playing with her hair is pretty minor, but if she does something like re-approaching you before she leaves or she asks you questions about yourself etc., those are HUGE.

Remember to watch for a handful of these, not just "she touched her hair, she wants to bang me!" lol Good luck!
