The older I get, the more siblings I seem to have. Older sister and younger brother that I grew up with: we all love each other and are closer now than ever. Half-sister that I didn't know about til I was 16: she's more like some kind of cousin or something, hard to view her as a sister really. I've found two biological siblings in the past few years. Met my biological half-sister, she's nice. Haven't met my biological half-brother, but we talk on the phone for long stretches a few times a year. Of the last three siblings mentioned, I am around the first one physically the most, but feel closest to the last one (even though I haven't met him in person yet).
