I did something bad after the openning..

So there was 2 girls in front of me ,i go to them and i say "hi" they said hi back.. then i have introduce myself and i asked one of them "are you shy ?" she answered not really then i asked "can i ask u a quick question?" she said sure... "are you single?" she said no
then she ask me are you out to pick up girls?
i said no , only u
she said... why me?
and i was like : because.... pause
and she said : because ?
because...my mind freze and blank and i said something very bad like : i saw you with your guard down..
i was like omg wtf was in my head..
oh fuck no no no ..anyway after 2 min more i took off i knew i screw it.
