It's seems impossible to interact normally with others if the entire world knows you've become wealthy. The interesting thing about SV is that you can cash out of a successful start up and still be completely unknown outside of a smallish circle. You don't necessarily even need to tell your family the scale of your success. You can just get a bit more generous at Xmas and donate more substantially to your favorite charities. People with simply appreciate the extra efforts rather than expecting/demanding access to your new fortune.
