“Wherever there are people
Giving gifts exchanging cards
I believe that Christmas is truly in our hearts”

Jose Mari Chan – Christmas In Our Hearts Lyrics on LyricsMode
This is one of the ways how to make others realize that Christmas is also a time to give love. How does it explain that? Because giving gifts and exchanging cards is a way to realize others that we love him/her. And Christmas is truly in their hearts because you give love.
