On my dad side I have a sister & 2 brothers , I really want to get to know her now she’s 15 & I’m 21 but the last time I talk to my dad “they don’t have a clue about me”. It makes me sad because that’s my sister and I would do anything to get to know her. I just seen her fb & Snapchat and I want to reach out to her so bad and get to know her. She’s In Mexico and I’m in Texas. Idk if I should just leave the situation alone or go for it. What do you guys think ?
