Yeah remember how when Samrat says to Gunjan that he remembered they haven't talked since a month and then acknowledges the fact that Sheena sorta reminded him (anniversary etc) and then he just cuts off from that thought saying its not important! To him the anniversary isn't even important all he cared, as we saw today, was to not make Sheena mad if she knew he had forgotten.
I know that waz hillarious when Sammy said that i waz laughing so hard. Only if Sheena had herd that Sammy doesnt think think that their aniversay is imp.. And he remembers his anivarsary by remembering the fact that Gunji and him stopped talking at tat time..
