Tears, that's very nice of you to share.
You should say these to him because it's more important for him to know. Ye my dad is very strict too. He still complain when I come home late :)
It's hard to say how you feel. I have that problem too. Always hold things in my heart. But sometimes I just give my dad a warm hug and he know that I love him. So if it's hard to say things aloud maybe a warm hug can tell all.
I wanted to say that my dad might not be a hero but he the best person I can ever thank God to have.
Happy Father Day to all the people who still have their father around. Be thankful for that. Don't leave things till it's too late.
