Stalking poll

[brixtonbrood]

I have twice bumped into someone who is the spitting image of a moderately famous British actress whose work I admire whilst shopping in Clapham High St. I think it's probably her, but I'm not completely sure and it's driving me up the wall. I am extremely familiar with her voice so hearing her say something would settle the matter. What should I do if I bump into her for a third time?[Poll #691010]
