Last week when I was in San Francisco we were eating at a resturant and sitting rather close to another table since the restaurant was quite busy and we didn't want to wait for a more private table. This would have been been all right if the 2 guys beside us weren't having such a deep conversation that we could hear every word of. They were talking about relationships etc and it just felt like a conversation that we shouldn't have been hearing. Needless to say we finished dinner quickly and left.
