There are just some people who are clueless about money and logic.
Example 1.
Me: nice apartment. how do you afford it.
Her: Yeah, I pay the whole rent out my money from my salary.
Me: I didn't know that your job paid that well
Her: Well it doesn't pay well but my father helps me with my car payment, insurance and some other expenses.
Me: So actually you do not really afford it.
Her: Sure I do, like I said I pay the rent with the money form my salary.
Me: Do you know what the term fungible means?
her: No
Me: I didn't think so.
Example 2 (a very intelligent in technology) friend.
Me: so how is it going.
Him: Pretty good, although I just took my RMD the other day and most of it went to pay taxes. Depressing.
Me: Do you take QCD? (Qualified Charitable Distributions). You said you give a lot to Charity.
Him: No, I itemize so my charities (around $12K), mortgage and property deductions come to more $2000 more than the standard deduction of $25,900.
Me: yeah, but if you took the standard deduction of $25,900 and the QCD you would reduce your total taxable income by $12K and come out ahead.
Him: Yeah, it would reduce my taxable income, but then I wouldn't be able to deduct it as Charitable deductions.
