It's not a big deal, bro. If she wanted it, just do it She is not your enemy, so kneeling is not a problemSeriously bro....this kneeling thingy is western culture....
If she wants i will propose but it doesn't have to be fully western. So, i'm not gonna kneel.
Another thing is....how can i explain. It might be a weird but. Since childhood..... grandma always said things to me like. "You are grandson of a war hero, (kimseye eywallah diyemezsin) you can't kneel before no one" and stuff like that. It made a impact on me, i guess.
