So I thought of being little different and compliment this chick (18 years old) about something, I rarely do that. To be exact, I wanted to compliment her on the way she smiles slightly and closes her eyes right before a kiss.

Me: The other day I was talking with my friend, and told him that there is one small special thing I like about you
Her: I know, is it ...blablabla... ?
Me: I am not that superficial. It is something that you do. You know nothing.
Her: Whatever it is, did you told him about our situation blablabla? This seems so funny to me, I would never think that you're 26 years old.
Me: I did, I don't complicate things in life. Haha, think or do not think whatever you want. Well I have to go now, night night.

What is that? A sign of insecurity maybe? She had some bad experience with an older dude when she was younger, and has made her very careful.

It seems like she was more concerned about the fact that I was talking with a good friend about her, and the way I was trying to be a little nice and romantic seemed childish to her.
I really wasn't expecting an outcome like that.

pffft it's just a shit test. Standard for girls to throw them out every so often to try and see if she can get you to react. You have 3 options when these occur.

Ignore: Ignore the shit test and just continue the conversation = its neither bad nor good really altho you run the danger of her persisting with the shit test and thus you will have to choose to react or respond.

React: BAAAAAAD. Reacting would be something like this "Oh is my age going to be a problem?" or some shit like that.

Respond: Good, builds attraction and makes you seem like more of a challenge. Something cheeky like "You'll just have to learn to keep up."

Shit tests get much easier to respond to with practice. I wouldn't call myself a pro at it but im much better the I used to be which was 100% pure reaction.

I wouldn't call that a shit test. You let her lead the conversation by avoiding to give her the answer. Instead of giving her the compliment you avoided it by saying "I am not that superficial. It is something that you do. You know nothing". After that, she was leading and you were following.

Besides, her lack of interest in the compliment was just that - lack of interest. Compliments don't take you anywhere, especially not if you try to make a big thing about them. If you want to give someone a compliment, just spit it out and continue the conversation as if nothing happened.

I am not a huge believer in shit tests.

Giving her some power were my intentions, cause lately I was the one distant, and not replying to her texts for 7 days and stuff. She is always responsive, and I wanted to show some affection.

I just don' get it, what was so funny, and the thing about the age, I don't get that too.
