Hmmm (does the calculations) You're 1 meter 70 centimeres, and gonna be 2 meters one centimeter? I honestly think you're not gonna grow into an NBA player height suddenly from your size. I'm currently (does the calculations) about 5'3" (if I've done the calculations right).
You don't know your dad? Hmm, I guess that's regular in US and UK... (damn capitalists have no respect to family). Okay, sorry.
PS. I get that 1'2" for example, is higher than 1'11" right? It's like 1.2 and 1.11, I guess... Maybe I'm wrong. In any case, I'm about 1 meter 77 centimeters, do the calculations yourself.
