OMG OMG this might actually be happening! She gave me her business card for her day job! I think she wants me to contact her!
OMG OMG what do I do now???
But seriously, maybe wait until thurs or fri and then call her and then go for a drink or fri eve. The worst case scenario is you have a drink and nothing happens, or she says no & you embarrass yourself. Best case is love-making. So doing a cost-benefit analysis, you have to call her.
