How to act like your parents are millionares?

I dont recommend doing this. You'll never be able to keep it up and your life will be one big secret. You'll never be able to really get close to someone.
You don't talk about money, and don't act overimpressed about little luxuries.


Answer:
Not sure why you'd want to...
but one element would be to act as though you were well educated (like forming questions properly, correct spelling, ... and awareness of current events, history, other cultures and languages, and so forth).

People tend to become wealthy by learning about their world and how to use it to their own advantage. They pass what they've learned on to their kids, and know that a broad-based education has enduring value.
Don't, all you'll be doing is living a lie, and as this lie progresses, you may even begin to believe, and you'll ruin your mind. Be happy with who you are, you were made for a purpose, and apparently that purpose was to not have millionare parents...What you can do though, is work hard, get a good education, so that one day, when you have kids, your kids may be able to say...my dad is a millionare! And that will be the truth
