6 Sep Monday. Pasta sauce went bad.

I often cook pasta because it's easy to cook and I can buy pasta sauce. I don't need to
make the sauce which tastes good. I just started to cook so I'm not good at cooking.
I wanted to cook pasta today as usual. I boiled noodle, prepared paprika and onion and
took out the sauce but the sauce smelled bad. I think it went bad. I should have put it
in the fridge. I had to buy new one to eat the pasta.
