It does seem to be an obsession with some people... as if they rely on this information for themselves for some purpose. As to what purpose it serves, I have yet to figure out! I guess if that's your cup of tea, then great, but it's not for me. I hate it when people try to estimate how much i make based on where i live, what i do, etc. These are off-limit conversations. In terms of a love interest, that has always been a deal-breaker for me!
And i agree, donsbon, it's funny that they have no idea how much student loan debt, as well as other struggles, i have!
