I recently came out to my 24 year-old sister and her BF. Out of the blue, she asked me whether I will still love her when she moves out. I said yeah, and then I asked her if she'll love me no matter what. My sister AND her BF said, "Are you finally telling us that you're gay?" I said yeah and my sister was like, "WTF took you so long? I've known since you were 8 years old..." Well that was easy. LOL Nothing much to it but this shows that some siblings known ever since your early childhood
