Finally talked with another foreign expat woman today but the conversation was more brief today. What do you feel about it

Today I again went to this luxurious mal UB City in our city Bangalore in India where we can meet many foreigners who are expats here as Bangalore is a major metropolitan city. I talked with several expat women there like an American woman and recently a German woman. Today finally I again met another white Caucasian woman in the mall. She is a Law student who is studying in Bangalore and she is from Germany too and as you all know I am studying MBA and living in Bangalore but born in Siliguri in West Bengal in India. She is 20 and I am 23 so she has been the only expat woman so far who has been the closest to my age. The previous American woman was 29 and the recent German one also 28-30 age range. Of course 28-30 is perfectly fine for me too as I am an adult now and its still close enough to my age. With the expat woman today with whom I talked, she was really friendly to me too and the conversation was just casual about telling about each other but the conversation was shorter than my previous conversations with expat women because she was actually shopping for dress instead of sitting in a Cafe. She is really pretty and unfortunately we couldn't connect further on Instagram or something as we just met and I really want to talk to her more now and get to know her more but due to University schedule and stuffs I don't get to go to UB City that frequently.
