What I do have a problem with is people announcing why they're selling something. "My kids need Christmas presents." "I need to fix my washing machine." "I got laid off and need cash instead of stash." "Baby needs new shoes." "My medications cost a lot these days."
Yes, these are all valid reasons for selling stash. But when this is the first thing I read before reading what the person is actually selling, it smacks of manipulation to me. "Buy from me because I'm manipulating your emotions into feeling sorry for me." It bothers me. And I usually read no further.
Maybe I'm overly sensitive to manipulative/guilt-tripping behaviour. Maybe I'm not. Anyway, just state that these items are for sale. Let the potential buyers decide if they want to buy based on the item's merit alone. Too much information is not a good thing, at least to this potential buyer.
