I sometimes throw away my lunch so that I don't have to eat it
Why would you waste food like that?
I'm a man of my word, I say I'm going to do something I do it.
It seems a little wasteful to just throw it out though. You can always save it for later if you do not want to eat right now.
I don't care, as long as I follow through with my word it's more than enough.
I think that you should just save it for later if you are not hungry now. It is okay to not eat, but I do not think that it is okay to waste food like that.
