Complicated childhood

The following day my mother called me, in the middle of the night. When I saw her name on the display I immediately thought I misread her name or that I was still dreaming. However, when I accepted the call and heard her voice I got the confirmation I wasn't dreaming.

"Sorry for calling you this early. I didn't sleep at night." She said with a low voice almost as if she was miserable.

"I can't stop thinking of your sister..." she took a brief pause to sigh deeply. "I had never noticed."

I took a long deep breath as well, still sleepy, I rubbed my eyes to wake myself up and then sat on the bed.

I didn't know if I could trust her but at least that was a positive step forward she made.

"I didn't notice it either. But that doesn't mean she faked it or that she wasn't feeling attracted to women since the beginning." 

My voice came out a little hoarse and quite low.
