How can you tell if a girl is interested?

YES this is my type of question. I have read a pycology book called body language and it explains signals that women can give off that she likes someone. There are 13.

1. Self touching, she will touch her hips or stroke down her dress or hold onto her wasit to pull it in. It shows that she is interested in you and if you play your cards right you could be touching her in the same way soon
2. Exposed wrist. The wrist is a delicate and soft part of the female body, showing this off highlights her delicate side and trys to show it off to attract you
3. The over the shoulder glance. This position of the head looks like the female bust which is flirty and used as a sign they are attracted to you
4. If a girl is sitting down and she is sittong on one leg that has the knee pointed, the knee is often pointed subconciously at the man she finds most attractive in the room
5. The limp wrist. Shows she will let you look after her and dominate over her
6. Handbag close to you. She trusts you with her personal possesions highlights her respect for you
7. Playing with the hair. She is nervous around you due to attraction
8. Stands up straight and sticks her chest out to highlight her feminimity
9. Holds her waist in to try and make herself feel more curvy
10. Gentle touching, she may gently stroke your arm or when you make her laugh she will pat your shoulder or gently hit your chest etc
11. Pouting, she may pout her lips around you she wants a kiss
12. Eyes half closed and a smile. This is the face a woman pulls when she has an orgasm, she may pull it if you make her laugh or when she says hello or goodbye
13. Shoe fondle. If she is wearing high heels and is slipping it on an off her foot.

These are signs that a girl likes a man when she is around him. Look out for them

Hope this helped
