Where are all the real men?
If you are male and you have nephews, grandsons or even sons who are being brought up either by a single mother, or a mother plus uninterested male, please take them camping. Teach them how to pitch a tent, read a map, light a fire, catch a fish and shoot a bow. If you don't know how to do these things, then learn together. You can't rely on someone else to do it and it desperately needs doing.
It's not something a mother can do, or even necessarily will realise her sons need. She might have younger children, lack of funds, or just not have the motivation, inclination, time, effort, energy or knowledge to lead those kind of trips. So you might not be asked to do it, much less nagged into it but do it you must.
If you don't do it, the young man might grow up looking for risk and adventure and seeking it in seriously unhealthy places.
There, that's my appeal to the world done for this decade.
