It's nothing, really.
Just that now, even Sayaka calls me 'oba-san'.
I was sitting on the floor near the barre, facing Lika and talking to her, when Sayaka said ever so politely, "Excuse me.. Oba-san?"
We had a good laugh when I complained to Lika though.
Even Sayaka burst out laughing.
Thanks a lot, Gino.. xp
