light xbow
Hello!  I'm so glad you stopped by and said "light xbow!"  I don't get many guests around here, and it's even more rare that I have a guest come by and mention the name of a random weapon.  In fact, you're the first one!  That's great, because I love interesting people.
Is there are particular reason you stopped by to say "light xbow?"  Perhaps you want to trade this weapon?  I assume so.  If so, which of my items were you interested in?
While you're here, we might as well chat, right?  I tell you I had this very silly experience recently I'd like to mention.  Just yesterday I walked into a McDonalds, because I was hungry you see.  I walked up to the counter, looked right the server, and politely said "McDonuts."  I tell you the look on that lady's face was quite rude.  She twisted her mouth and frowned, and looked at me like I was some sort of crazy person!  "We don't serve McDonuts, sir."  Was what she muttered afterwards.  Of course I knew they didn't serve McDonuts!  I wanted to pay 
them with McDonuts!  You know, get a burger, give them some McDonuts, get my change, and be on my way!  So silly.  I had an idea that perhaps they would not accept McDonuts as payment, but it never hurts to ask!
And that is why, my dear friend, I am not at all confused by your somewhat cryptic utterance of "light xbow."  I assume that I assume correctly that you would like to offer a light xbow for one of my items, yes?  Just let me know what you are interested in, and we can see what can be done.  I am not looking for a light xbow in particular, but every man has his price! 

Thank you for stopping by, I do enjoy these visits!
