What do you do when someone won't listen to you?

somehow you have to wait till youre in tune with your mum or dad. your gonna have to see what makes them pause for thought what makes them freeze and consider something. maybe if you say sonething and they change the subject you need to remain calm and say again if theres still nothing after three or four patient attempts they probably cant find a comfortable or true answer fir what yer asking and it may be better asking someone who you can trust to answer or has some knowhow on the subject. all really depends what your asking how and how you approach people
