MFW I found a bug that has been dragging me for several hours....and it turns out to be a typo

That happened to me recently. A bug in a project for my c++ class was driving me crazy for 2 days. I walk into the TA lab, we both can't figure it out. Then we both notice a missing = that should have made my code var1 -= var2.
That feel when you hate yourself but are just too happy to care.
