Dad is the only person who toil his life and strives hard to make you happy and comfortable all the time. Sometimes we would get so mischievous and fail to value his feelings. But the heart would began to prick us for hurting him. Dont overload your heart with the regrets, instead send a simple “Sorry Papa” image to your dad and make him realize that you didnt mean to hurt him at any point. You can also use this sorry papa image as your wallpaper.
