I think a mom and dad's word to their son is one of the most important you can receive. And you better take it in and use it, because if you miss their guidance you might miss a lot of benefits.
I know because my parents guide me every time I talk to them, and honestly sometimes I don't listen and the results are never good. So take it from me and listen to your parents. The reason being that they have been our age, they have lived it all, they have experience, and we are only starting our lives. So when they say stay away from strangers, do it. Don't play with fire, don't do it. Simple!
Just listen to them and you will be fine, no harm done there, its not gonna kill you to obey sometimes
