Dont text, call. its much better, shows confidence and that your alpha, you dont have time to fuck around hitting buttons.
So give her a call, and either introduce yourself indirectly, or ask her if she is herself indirectly...IE what I mean is, something related to your meeting..
DONT say "hi this is steve" or "hey is that jane?"
Say something like ...(for example)
"Hey its the winner of Masterchef, Im calling to congratulate you on wearing the most ridicoulous red polka dot dress in the world"
IE, you were the cook at the BBQ and she was wearing some silly outfit, You havent given me much to go on
So replace as neccessary...She should realise who you are pretty quickly if you made that much of an impression, if not, you can give her a little hint by teasing her about something that happened...What you can do is then play along with this little story, and set yourself a date up..
You could day for wearing a silly outfit she has won a cookery session with you the winner of masterchef, and when would she like to redeem it? Sets you up for a prefect date, get her to yours, or go to hers, cook something small, then take her upstairs
You sir, have now F-closed.
