My Body Thought I was Nervous

I was happy to see my 1/2 brother (HB) today and talk with him. I'm used to having lunch with the bio-dad but this was different....this felt like a test. It was The HB's idea...he wanted to see what I was like. I guess my body was nervous - i didn't feel nervous but my stomach was playing havoc on me! Once I got there I felt at ease. There was only a few awkward silences but we laughed and joked and had a really good time. He's cute and smart and funny (like me - lol) . He doesn't live in town so who knows when I'll ever see him again....but I left wondering why I was ever nervous.....
