Approached twice today, both times in the same bookstore about 10 min apart(not in sight of either of them).

Learning Game: Daybang(Not done yet)

First approach, girl was reading some book behind me, and I grabbed a book from the shelf and accidentally knocked some over. I jokingly said you didn't see anything, and she agreed and I said thanks and said we were partners in crime. I then said I like her shirt(it had a possum on it) and she said her friend gave it to her, and that she outgrew it. I said nice and asked what she was reading, and it was some book about physiology and said she was really liking it. I then asked if she wanted to grab a coffee upstairs, and I'm not sure where I went wrong here. She said she already had one and looked uncomfortable, and then I wasn't sure what to say so I just said thanks, have a nice day( a little awkwardly), and walked away. My question is why would she be uncomfortable and how can I avoid that? I don't care that I got shot down. The conversation was going great until then, like good vibes, but I'm not sure what I did to make her feel that way.

Self-Answer: Maybe it was an unconscious facial expression on my part, since I felt disappointment. Or it could of just been an issue on her part on being asked out? I think I could have done better controlling my disappointment so that's what I plan to work on.

Second approach, I was waiting in line at checkout to get a book and there were these two cuties in front of me. I asked one that was closest to me if they found anything good(girl 1), and she said yeah that she found an artbook for her friend(girl 2). I then asked girl 2 if she was an artist and she said she was in art class. I then asked about what kind of art she does, and we chatted for a second. She asked if I was an artist and I talked about a beginner sketching book I got, and how it was daunting. I then asked if I could get her number and maybe get some sketch tips from her sometime, and she said yes! I got her number, and then we traded names. I fumbled a bit after that. We still had 5 more minutes in line, and it was hard to keep the conversation going, but I managed to talk about travel a bit. I think I may of messed up by engaging so early with the long line, but it felt natural. One thing I messed up is I had to ask her name again, since I was so focused on the conversation. Now in hindsight, I think she might be a little young for me since she's in college(like 8-10 year gap, not sure what year she is). I have the following questions. Should I ask her out for coffee even though I will probably bomb with my low SMV(no job and living with parents, but I'm still working on both)? Is there an easy way to confirm she's old enough for me(like 21-22?) I don't want to date younger than that. How do you even tell a girls age when approaching, because I've seen 25 year olds that look 20 and 20 year olds that look 30? I ideally want to date 23-30 age range. How long between number and asking out do you wait?

Self-Answer: I should ask her out to coffee and bomb just for the experience. I could straight up ask her if she's graduating soon. Not sure how to tell age, maybe look for signs of age in face(light facial lines and such? I think I should text her tonight and just ask her out to coffee tomorrow while I'm still on her mind, cause she'll probably forget about me in a day or 2.

Final Question: This is the second weekend I approached at the same store, how often do you change places to deliberately day approach? Should I go to a different store?

Self Answer: I should probably try a new place every week so I don't restrict myself to one place, the reason I decided to try this place is because it's a cute bookstore that women love. Thanks.
