What should i have done in this situation? ?

So today I was talking to this sexy women :) She told me she was 23 (im 18) and she was in business school. So I started flirting she flirted back then I asked for her number I got it and then her DAUGHTER comes up and say mommy can I get this shirt. I was terrified so I ran literally then she texted me. What should I have done differently cause I made the women feel terrible?
