So, this make me wonder whether is it normal for a 'father' to receive a wishing "Happy Father's Day" from someone who is not his daughter or son.
Well, come to think of it, as long as one is father, he is 'qualified' to receive father's day wishing from anyone, even he or she is not your son or daughter.
Important thing here is if your wishes can make a father feels 'great' or 'happy', even you are not his son or daughter, why not?
This post is dedicated to this 'someone' and my late father, who passed away last year.
I miss you dad, "Happy Father's Day to you" daddy. I wish to mention part of my tribute to him below:-
爸, 再见. 愿您有个更美满的来世."
