Well, sometime i am afraid and sometime i am not afraid. Actually, i don't want to tell my parents about my gambling, but if suddenly my parents know about it that i am playing gambling, then it has no problem but i am afraid of it that may be my parents don't like it or may be they have no problem for my gambling, it is my fear. But i am not sure about it, otherwise, i am not worried for any others like my friends and others and i do posting on gambling.
You need to tell them about gambling because might they help you. If you are hiding like this after heard about gambling that you are doing then they will be hurt so i want to say that you need to tell them.
If you are not addicted to gambling and just playing for fun then no need to share this with your parents. But if you are addicted and trying to come out better you can share with them. But posting our gambling activities on facebook or twitter or other social medias is not good. It depends on country and person. in some country the gambling is illegal if we post our activities then it will be a big problem for us. And in some countries, their religions will not let them post. Like this, we have many problems, so better we can away from this social media is safe for everyone.
