the perfect excuse

I was chatting with a pal of mine, Scott, when he reminded me of a fantastic line that will work in every awkward situation. If a conversation gets difficult, remember the words of Christian Bale in the classic film, American Psycho.
[Just after breaking up]
Evelyn Williams: Where are you going?
Patrick Bateman: I am just leaving.
Evelyn Williams: But where?
Patrick Bateman: I have to return some videotapes.

This sage advice will get you far in life. Trust me.
