ive got a half brother and 2 half sisters, so far ive only met my half brother, hes 5 years younger than me, u already are off to a good start as ur are friends on facebook so u know what he likes/is in to

arrange to meet in a pub for a few drinks, it will be awkward at first but after a drink or 2 you will be chatting about ur interests and u can tell him things about your dad that he may have questions about

ive still got to trace 1 of my half sisters who is 1 year younger than me, unfortunatly her mums boyfriend after my dad adopted her so her name changed which is making it harder

my other half sister im in contact with on facebook she is 16 (im 33) and lives in america with her mum and my dad, we chat all the time and she will becoming over in 2 years time to meet all the family

your half brother is prob curious to know/meet the rest of his family esp if he is a only child like my sis who only found out after chatting to me that she is aunite at 16 years old to 8 neices and nephews who some of are older than her and she has a great neice and a great nephew

your half brother prob just wants to know his family roots and find out where hes from
