Do you cut your parents lawn when your older brother lives their? I feel obligated to cut my parents lawn even though they have a lawn mower and my brother lives with them but doesn't cut it. I sharpen the blade to their mower(basic maintenance) but it seems that I am the one always cutting it at the end of my long work day. I don't have a problem cutting my parents lawn for free but when my bro is living their I just feel that he should be doing it. Any thoughts?
