tldr: pulled but didn't close

So on Friday I was tired, was thinking to go to sleep, but Spring energy filled me and I decided to go out. I was after a lonb break, so to warm up I visited few other clubs and approached on the street in front of them. After few approaches I've moved to my destination. There were few girls I've approached before, so I said hello to them.

Here I saw a girl alone who wanted to enter into the club, she was tall and slim with attractive face, dressed like a emo hippy, I think she was 8. I started talking with her, asked why she isn't inside. I did some kino, asked about locked she was wearing.

Then I entered in. Started dancing. Tried to be funny, joke with neighbor girls. From time to time was going out in front of club to smoking area to talk with people, mostly with girls, but with guys too. I'm still not very comfortable talking in loud environments inside the club, I prefer outside.

There were some rejections, one girls was married, showed the ring. To the end 2 girls came, one 5 (fattie) and one 6, the 6-th girls was looking to me from time to time, so I opened her, she was from neighbor country living in hostel nearby. She offered me potato chips and beer, I declined beer because I don't drink. At the end she said they have a bottle of wine, if I want to join them, I politely declined.

Later I was surprised to see the first girl, the 8 doing some DJing. After she finished I approached her. We talked for some time, until the venue was closing, she had some DJ friends and was talking with them from time to time.

I offered her to ride home together, she agreed and in process I offered to cook for her, we visited a 24h marked to buy ingredients and went to my home.

She always kept asking how old I'm am was not believing it when I was telling her the truth. I don't know, should I agree to the age she first guessed? (She guessed 6 years younger)

During cooking I kissed her first time, but I had to distract myself from her so that food will not burn.

After we ate I started making out in the kitchen, tried to take off her shirt, and then she said that she urgently needs to go home, because she has alcohol headache. I asked for phone number but she gave only facebook. She called a taxi I hugged her and she left. Later she liked few of my photos in fb.

Now I'm planning a date with her.

Conclusions:

I could have closed her, she was clearly DTF, but I missed buying temperature during cooking, should have listened to pickup gurus that a yogurt will be enough, and I had a yogurt and she was interested in yogurt, I just wanted to impress her with my cooking, it can work on cooking date, but on pulls from club when people are tired it doesn't. (don't be validation hungry man)

May be I don't know how to create sexual tension, or I was too fast to try to take her shirt off.

What do you think? Any advice or comments?
