What are some ways I can tell someone that I never spoken to that I'm his son?
I am your father:o
Just say I'm your son
Be like "oh hey remember me, yeah you made me, im your son" i've always wanted to say that to my biological dad, of course instead of son say daughter.
Just strike conversation with him, when you feel the time is right, tell him you have big news...
Is his name luke?
"Hey, I've never met you,And this is crazy,But I'm your son,So call me maybe"
