You disowned me so I didn't think you'd want anything from me.

The story behind this conversation is that Keira went to spend the weekend with Rick and came back with Birthday presents and got a cake and ice cream. Mikia didn't even get a real Happy Birthday from him. Other than him telling Keira to tell her for him. Now their birthdays are only 4 days apart. And we have 2 working cell phones in the house. Why couldn't he of text or called him herself? I mean was it really that hard to do?

But the biggest issue I have is how can a parent, father or mother, so easily do that? Oh, you disowned me so okay? Yeah no...I would be all up in the kids' face wanting to know why and what can we do to fix it. Most real parents would. But I guess I shouldn't be all that surprised really. This is the same stunt he pulled with Jaymz too. Just walked away like they were never nothing.

And I was seriously considering asking Rick to let Derek adopt her, but you know...he isn't going to get out of the $14189.11 in back child support that he owes these kids that easy. That's what the general opinion on why he is doing it has become. Or alienating the kids so he doesn't feel guilty for not paying. Yeah...
