A wonderful trick not known to everyone on Facebook enables you to show a large number of symbols that are the hearts of coming out and floating on the screen, this trick lies in one word is Xoxo, this word in the original meaning kisses and hug, when you say it to anyone you mean it to include Hugging it, and now on Facebook once you write it for example in a comment that shows hearts and floats on the screen.
Like write in the attached (xoxo) I was overwhelmed ok
If you try to press the word again these hearts appear without having to comment the same word again.
