Thank You

In our daily lives we have plenty of opportunities to say Thank You.
Do we though?
Do we take the time to thank that other person. I would love to say that I say Thank You every single time it is warranted. But I won't, because I'm sure I don't. Sometimes you do things without thinking and then try to remember if you did or not.
Today, as an example, my sister and I were shopping. We were waiting for the typical "take up the whole aisle" couple to move aside so we could pick up what we needed. When I saw an opening I jumped into the section and started grabbing what I needed before they started again. My sister yelled to me to grab something, she called it by name, one that I had never heard before. I'm looking frantically up and down the shelf looking for this mystery item. The girl next to me (who had to sneak in too) pointed it out to me.
I said Thanks, or did I.
Later it came back to replay in my mind (why do we do that anyway) but did I say thanks. I have no idea.
So thank you - Thank you to the girl who pointed out the food box to me. Thank you to the person who let me cut in the traffic line. Thank you to the person that complimented me on my gorgeous daughter. Thank you everyone for everything. There, I think that might cover it. I'll replay it now and see.
