650 dollar bills is a lot of singles, it could feed a man for a month or more, or provide enough gas to drive across the US, it must be a lot of money, but it's quickly lost when it comes to basic needs like housing, healthcare and education.
For those saying it's not a lot of money, I shall gladly accept your donations.
$650 would allow me to buy myself a new office chair, or sort out a DIY project. Sure, I can save for these things, but if it's an inconsequential amount for you - it's an amount of consequence for me.
