Girls do some weird things to express feelings. Sometimes they do things just to do things.
Let’s face it, there are a lot of things we will NEVER understand about women, and by no means does that make us love them any less. But sometimes their actions are so far beyond any normal rationalization, that all we can do is sit back and stare with wonder and awe. Girls licking foreign objects in public is one of these beautiful phenomenons. We can only imagine what Freud would have to say.
