Writers love using analogies. Like shortcuts or quantum wormholes, analogies can get you very rapidly from Point A to Point B in a manuscript. In conversations, however, they are much less effective. Instead of helping you communicate, they tend to add layers of abstraction onto a process that is already abstract.  Nobody likes feeling confused, and abstractions tend to have that effect when they're used in a conversation.

My point? Leave analogies to the writers. We're trained to use them safely. When you're having a chat, speak in concrete terms. The people you're chatting with will appreciate it!
