On father's day I didn't even think about doing anything for my dad.
Why not? Do you not care about your father?
My dad should be more appreciative toward me.
I'm unfamiliar with your family affairs. I do know that expectations can kill a lot things, so make sure to gauge yours appropriately.
If he loves me, he should be happy with what I do.
Do you realize how much you're hurting your dad by ignoring him on father's day? He may not be happy with that pain you've made him feel. Would you like a loved one to cause you pain?
