Riddle: Arrows are a part of me, but bows are not. You may enter, but not leave. You can't go in, but you can escape. What am I?
Answer: I am a computer keyboard! I have keys with arrows on them, an 'enter' key, as well as an 'escape' key. However, I do not have keys with bows on them, a 'go in' key, or a 'leave' key.
