"Oh, you're selling an old kitchen cabinet? Sounds like you're doing pretty well to be able to afford a kitchen remodel. Must be nice."

"Wait, you don't have time to come to my kid's birthday party, but you're out skiing so much that you had to upgrade your skiing gloves?"

I'm not saying it's right or makes sense, but there are a lot of contextual layers and subtle subtext inherent in other people's relationships that may not affect your own.

I don't like spamming people that aren't specifically looking to buy something. How much or how little I spend on something feels a little private. There are lots of things I wouldn't care about as much.

What if you're selling something that they gave to you as a gift?
