Hey there! Are you interested in my giant Oak mirror?
yeah! it looks nice.  I can offer 35 and pick it up myself, is that good?
Hmm Well I bought it for $100 and was trying to get $45 for it. Could you ateast do $40? 
that seems reasonable!  $40 it is
Okay that works great. You're still coming though my place and picking it up correct? if so this price works well!
yes I can pick it up :)
