You have to put the crossed out words before the uncrossed words.
The idea is that you initially type what you really mean, but then have second thoughts and cross it out to replace it with something more acceptable.
Good: "I let my children eat as much junk food as they like because I am lazy and neglectful freethinking and alternative."
Wrong: "The children spent the afternoon playing backgammon watching horror movies."
I keep seeing people put the crossed out words second, and it's WRONG.
