even try to show up to see them?
I just don't understand how any parent wouldn't want to call their bio child. Whenever my bio and step kid are with their grandparents for visit, I still call because I dont want a day to go by without me telling them that I love them and to see if they are okay. Even if they grow up and decide they don't want to talk to me, I know I will still call (even if I have to be put on speaker phone so they can hear me) just so they know I'm still there for them.
I just don't understand how any parent could claim that they miss their child but doesn't do anything to show it! And I mean going months and months without trying to contact.
