So I got sort of a day game question regarding a girl that working at one of my customer workplace.
In the beginning I have only seen her in the hallways and just smiled and she smiled back. Recently I have managed to meet her and do quick conversation with her like "how was your weekend blabla". Mostly I think I have kept my body language open, calm and confident and held the eye contact (not always at her but mostly). I perform best when I improvise and don't plan what to do.
When I have helped her with work related stuff she also seems to be comfortableby standing very close to me. I'm not sure if she acts like this to all or just to me. I haven't managed to do any kino escalation.
On one friday I think I caught her looking at me when walking by me. When I turned my head at her, she didn't know where to look and say, so she just said "have a nice weekend" and I replied "you too, and do not do anything silly this weekend" with a confident smile.
Another day I asked her about how the weekend was blabla and she said that she was going to celebrate her birthday the week after. She was going to have some cake at the workplace and invited me to that if I was going to be there that day. I think I said something like "Yes, I will" and smile.
The next day at work she was preparing her birthday stuff and I managed to see her alone and congratulate her (shake hands). She replied something like: "How formal" with a smile. My plan was to shake her hand and give her a hug as a present, but I chickened out! Good or bad?
Then I asked her about how old she was going to be and she made me guess her age. First I said "3...?" with a smile, and the guessed 26 which is a little under her real age which she liked. Then she asked me about my age and I made her guess too, and she thought I was over 30 (I'm turning 30 this year).
Me: 30+ ? So I look that old?(calm and playful)
She: No, you just look so grown-up.
The day after her birthday I also sent her a text:
"Good morning

How was your [age minus 5 years] year celebration? I will not be available at your workplace today due to other customer visit blabla. - My name
- She replied positively about 10 mins after.
I think she shows interest in me but sometimes Im not sure if she's just like this to everybody (which is not how I should think). What's your thoughts?
Should should I create more attraction before I ask her out?
And how should I do it? Just go to her office and ask directly I she want's go out for a coffee/drink at xx day?
I also have the opportunity to join her and her coworkers for lunch. How should I "perform" under a lunch situation?
