Yes it is possible to pick up from talking about about these subjects! hahaha
Did this on wednesday night

This pick up did reinforce the point how they will give you a wealth of information to pick them up with. For instance:
She mentions how we have been talking a lot about politics, one of those "taboo" subjects of "Politics, Religion, and Sex". So then naturally it is easy for me to pick up on this thread to then talk about Religion, quickly followed by talking about Sex.
Later we had this list of cocktails in front of us, I'd earlier noted their dodgy names, she asks me if I've ever had "Sex on the Beach". So I talk about fucking on the beach for a while, and then I follow along with this thread with all the other dodgy cocktail names.
