I just got a call from the aunt who, when my birthmom found me in 1998, was horrendously upset. She thought that my birthmom had no right to be any part of my life, that she was horning in on my parents. This was... a big problem for this aunt. Big enough that I ended up not inviting my birthmom to my wedding (to ex-husband - she found me just a few months before), because my aunt was so insistent that it would be a terrible thing to do to my parents. (I had my birthmom at my recent wedding to Adam. Went just fine. Then again, we all had several years to get used to each other.)
My aunt called me because she remembered that my birthmom lived in New Orleans, and wanted to make sure she was okay. She'd called my parents, who weren't home - and rather than leave a message and wait for them to call back, she called me. This is the first time this aunt has ever called me, IIRC.
And it's because she's worried about my birthmom, too worried to wait an hour for a callback.
