You obviously made an impact. Hopefully it was a good one... ;)
Well obviously, I must be unforgettable.
I lost track of a friend that I knew when I was in grade 3. 30 years later, we ran into each other on the street we instantly recognized each other. It means nothing.
Did you recognize her too? Is that because you thought about her during all those years?
Probably not. She probably has a good memory.
She probably has a good memory. I wouldn't read into it too much if I were you
