Are my parents too traditional? What the hell is wrong with that?

It's a matter of different values between the two generations and the generation gap. They will think, you are a girl to be a little more reserved, not married to the boyfriend's home to run, the neighbors will see gossip, the old man love face, you have to understand their pain, from a point of view is really for your own good! They see you take his family to send things, the heart is not too good to think, the family lack of your food, clothing and pocket money? Are you poor and can't afford to buy anything? Did you grow up without being taught not to take things from other people's homes? That must be what they think. In a word, they still feel that their own face has been hurt. Be understanding and talk about it more. Good luck
