Boys and girls playing together

Re: Boys and girls playing together

I've been told by mom since childhood to not laugh around with boys or play with them etc. So now in school guys ask me why im so quiet and dont talk with them ( I only laugh nd talk with girls) and only talk to guys when necessary for example school work, discussion etc.
I believe it's good that ive been told about this from an early age, bcuz otherwise i might have been too free with guys or?
