It doesn't seem to occur to you, jess, that you might have upset me too! My 'lecturing' as you call it was meant to be bracing rather than upsetting. If you find it upsetting that is a shame and I'm sorry for that, but it is not my fault that you interpret things as you do. You clearly have not read much of what I've written on here if you think me an unsympathetic person.
How do you think I acquired what you perceive as my "natural emotional resilience"? Just because I haven't told of the harder parts of my life on GN doesn't mean I haven't had them (may still be having them for all you know). However, I don't wish to play the emotional card. My points on this thread are to do with clear thinking as a way of dealing with pointless worry, and my last ones perhaps need a bit more explanation.
I'll put myself in your son's shoes (actually, I have been in a similar situation more than once). If I, as a recognised "competent adult" and "good planner" was about to embark on a life adventure such as you describe and a man – any man, including my husband or father – "la la la'd" about it, I would think their attitude patronising. Why is it different if a mother does that? I don't think it is. That's just my view and I'm allowed to express it.
