I'm looking for an idiom or expression for when people are counting other people's fortunes or money. Usually it's a gross over-exaggeration of reality stemming from envy.
Example: "He can probably afford 5 houses on whatever he's getting paid!"
Example 2: "Look at you. You must be getting all sorts of dates."
(Edit) I'm looking for something to use as a response to such assumptions directed at me or other people. If someone assumes I'm very fortunate at X (when I'm not) I want a response that grounds their assumption. It could be a quote or an idiom. I want something more eloquent than "Careful about counting other people's fortunes" or "People are always better at counting other people's fortunes than their own"

in place of the expression?
