I don't know how you guys are with your own dad... but i had this hesitation of approaching my dad. I couldn't hug him like i hug my mother... so easily. He is a cool and responsible man, no doubt. He is the first man to love me.
If my mother is my world then he is the light of my world.
Today i finally gathered the courage and hugged him and when i was about to pull away suddenly became i thought he would get awkward but do you guys know what happened.
He hugged me back, with the same happiness. I felt so overwhelmed and happy. The awkwardness finally disappeared. And now i know that i can approach my father same way like i approach my mother... without any reason.. without any occasion. Just like that.
All this time i just needed to take a step towards him. He was already waiting for me with open arms.
So if your still hesitate to hug your dad. Go for it. Now is the moment. Or you will keep hesitating all your life.
