Ok, I´ve put some thought into this and I still don´t know what to do. I´m gonna try to explain my dilema. I was adopted at an early age (two weeks giver or take, according to my mom), when I found out, I was ok, I figured my biological mom had no means to support a child, and so she did the right thing wich was give me a chance with a family that loves me. I was ok with the situation for years Recently, a friend of mine, whose dad is a very good friend of my dad, told me I have a bilogical younger sister who was born a couple of years after I was. My uncle (who was responsible for my parents getting me) aaprently contacted again to see if they wanted to raise my suposed sister. According to my friend, my parents refused to do it, because they were afraid that having a second child appear all of a sudden on our home would confuse me. So, long story short, I have a younger sister somewere, but my parents don´t know I know this, I assume they haven´t told me because they feel I would be angry at them for no adoting her too. So, should I ask them about my sister or let this slide?
