How can I convene a girl?
Remind her about seeing you last.If she doesnt have your number, she may not have any clue who you are when you first text. Try saying “Hi Stella. If you exchanged some small talk, bring it up. Stay away from anything negative about the situation when you met. Tell her how great it was talking with her.
How do you meet girls at a bookstore?
You could approach a girl and ask about the book shes reading or looking at. If shes distracted or disinterested, leave her alone. Many people go to bookstores for quiet alone time and dont really want to talk. If you end up having a great conversation, you can suggest meeting up for coffee and exchange numbers.
