I'm just curious, have it ever happened to you that you wanted to tell someone 'thank you' for something personal but felt too shy, inappropriate or awkward and never thanked them in the end?
Personally, it happened to me before. It wasn't until I started practicing small "acts" of gratitude (even if silent ones of which only I was aware) often enough that I started feeling completely comfortable in expressing my thankfulness and giving thanks out loud so openly and so often. So, I guess for some people it does take time and effort to be able to voice it. However, some don't even try. This is why the idea of the Thanksgiving holiday is such a good idea.
