Unfortunately, not everyone is strong enough to thank others, not everyone is capable of accepting a compliment with a simple thank you, not everyone is able to say thank you for something nice that someone else has done, it might have been a big thing or it might have been a simple thing as opening the door for someone, there is no harm in saying thank you to others, to be able to say thank you is a wonderful habit. It is a small deed which is highly appreciated even for small things. We all should say thank you more often and encourage others to do the same.
"None of us got to where we are alone. Whether the assistance we received was obvious or subtle, acknowledging someone's help is a big part of understanding the importance of saying thank you." - Harvey Mackay
