that's true for Americans..m not sure among Filipinos..or maybe it's just meh.
so, in the p.i., when a guy ask a girl out or a girl goes out, to maybe dinner, with a guy........... does that mean they're in-love?..........they don't know each other well enough yet........... to even say they're in-love. those three words should be solemn, truthful, and honest. I don't think I can say that to a girl unless I really know her and have been dating her.......... and I expect the same with the girl.
visiting a girl in her domain with relatives around.......... a guy would try to be like a sheep (in wolf's clothing). it would be very awkward, uncomfortable, and difficult for him to act or be himself. so, how can the girl know the guy better? it would be the same for the girl............ now, how would the guy get to know her better?
