this is what having nothing to do in the office leads to...
my older half sister stopped speaking to my dad (also her dad, different mothers) about 10 years ago now, and no-one's seen or heard from her since. i occasionally do a facebook search on her name, or have a half-hearted look around to see if i can find her, even though chances are she's changed her name, and i know it's a bit of a sensitive issue for my dad and don't think i'd be able to mount a full investigation without his knowledge. i don't really know what went on, or who was in the right or wrong (and don't really care), but there's been a growing curiosity about who she might be now, what she might be doing, for quite a while now.
someone had told me that friends reunited is free though, so, with nothing better to do, i signed in today and it occurred to me i could do a search for her there, having known which school she went to. so i did, and up she popped, and i sent her a message. she probably never uses the site, so probably won't ever get it, but it was maybe worth a try, just letting her know how to get in touch with me directly if she ever wanted to.
anyone else have any lost brothers/sisters/half-brothers/half-sisters? ever got in touch?
