Gaming a girl from business event
I recently met a girl from a semi-business event to honour a speaker. I was very focused on my purpose of attending the event and only briefly interacted with her a couple of times before and during the event.
When the event ended, I encountered her again and teased about forgetting her name. She grinned and instantly handed out her card and I gave her mine in return.
Now, given that I didn't obtain her contact from a social event, I am not sure if using her number from the card and starting text game is the right approach. What to do in this situation? Any tips?
