Masaegu,

Thanks again for you help.

I think I get it now. It seems logical now to think of it as being kind of like "he shouldn't waste what he has" or "it's wasteful for him to not be with me".
I was just associating it with recycling and that whole idea of not wasting food...so it wasn't making a great deal of sense. It's interesting to know it can be used in that other way in compliments like that and about people's activities or qualities.

Thanks again
