So, there's this one cute blondie girl working at a local coffee shop who I have developed a small crush on. I found out about a week ago that she is going to go study at a university about 80km away on the 1st of August (through her open IG profile), and the day before yesterday I made the brave decision of asking her out before she just disappears. I handed her a letter written on an old receipt with the message "Should we go get ice cream together some beautiful day?" as well as my number and first name. She smiled to me pretty widely after receiving it, but has not yet contacted me though as of now. How many days would you consider it to be "normal" to wait for a response from her, and at what point in time do you think I should start getting worried if she doesn't contact me?
