Mistake? or New opportunity!

It is stiill the same damn day. The day we get our blood reports backand there has to be a mistake in mine. it says my blood type is AB. my blood type is A. Moms was A and dads is A. so why is mine AB? That question has lingered with me all day long i waited until my dad got home unfortuatly today is always the day he gets home early and has pool leuge. so i might be up all night. While I was doing homework at the kitchen table I feel hands on my arms and then he said "Hey Beautiful"

I instantly reconized the voice as Daltons "Who's Tabbitha?" I asked.
"I don't know."
Liar. "you sure?"
"Yep. Whats this about darlin?"
i completly ignored his answer and pulled out my phone thanks to his brother i got pictures. "really cuz i think ya do" I handed him my phone then my dad walked in.
i walk out of the room because I know im going to gert my ass chewed out.
From my room i heared the door slam and a few minutes later my dad walked in and i asked "What is your blood type?"
"A. Why?"
"I got my blood tests back today. and it says that I am AB but i know moom was type A."
" I was worried about this."
"About what?"
" I guess your old enough to know now."
