appreciating your parents

Realize that your parents are human too, and have feelings just like you, that can get hurt. tell them you love them and appreciate what they have done by raising you!
 For younger people and adults, see a need around your parent's house and just take care of it. They will greatly appreciate it. Our parents spend most of their life devoted to us, so make their golden years one where you are there for them, sort of like a changing of the guards. After my Dad passed away in 2006, I really felt this with my Mom.

Take your parents out for a dinner, take them out on the town, something they want to do. basically I am saying spend some quality time with your parents. You are making lasting memories that you will carry in your heart always, long after they are gone.
