Thankful

What does it mean to be thankful? Perhaps we could all write on our blogs or facebook account that we are "thankful for...", but does that constitute sincere thanks for some thing? I don't believe so. If one were really thankful for... they would go and show it (show - meaning that they actually do something that constitutes some significant act such that anyone who witnessed it would know their gratitude). I would challenge all of you who read this, to actually go out and DO something to show your gratitude.
