The money thrown in the trash

I read an article about a woman who threw away 40.000€ by mistake. I don’t really understand how that woman missed such huge amount of money. Probably, now she regrets what she has done. Her husband must be angry with her, but on the other side we are only human, we all make mistakes in our life. But what you can do? Even though, that’s a lot of money, they’ll get through. What about people who don’t have a salary that would make possible to save something ? Sometimes salary is high enough only for paying the bills and for food. Hopefully, someone ,who doesn’t have a lot of money, has found the money she threw away
