Supportive parents

Today while I was in the waiting room an old lady told me that she should have kicked her daughter out when she turned 18 so that now that they're both older the daughter would appreciate and treat the mom better.  She sounded bitter and a little angry but she was totally serious about what she said.  It instantly made me thankful for how supportive my parents are and have always been (especially my mom) even after I turned 18 years old.
