My wife told me to throw the old vegetables away, and when I did she got mad. Apparently she wasn't talking about her parents.
So, am I understanding you tried to throw out her parents because of their age?
I appreciate your concern but they're fine. They are old and useless and that was the perfect angle to make a joke out of it.
This seems odd, I don't understand why you would want to joke about that. Do you really see them as being vegetables?
Ok, so I see where this is coming from. I got upset because my life is hard and don't have time for these old people around for much longer.
You shouldn't call them names and think they are useless just because they are old. You need to have more respect for your elders.
