A good place to flirt is while waiting in line, says Sara McCormack Hoffman. Hoffman, who teaches a class on the joy of flirting at the Open university of Minneapolis, say there are better and worse places to flirt. Another good place is in store shop or shop, where you can talk about merchandise. Hoffman says the worst places include bars, where there are high-pressure situations with loud music and alcohol, and the things you say may go unheard or unremembered.
