Yes, I have looked at the forum from time to time, as I sometimes feel that as the mother of grown up DC, I am a bit betwixt and between in terms of MN and GN (but definitely prefer MN), too young for the Stannah lift, but well past the weaning and toddler tantrums, problems at the school gates etc.
I find GN interesting but much slower moving than MN. It's a different demographic, which is reflected in the problems and responses.
There are a few posters who keep popping up on a regular basis, who clearly have issues with their DC, just as on here the DC have problems with their parents - the equivalent of the Stately Homes thread. I always feel, as I do on here, that I would like to know the other side of the story. You can't really know what is going on inside other people's families, just as you can't know what is going on in their marriages. Obviously, when giving advice, you have to assume that the poster is telling it as it is, and advise accordingly.
A lot of relationships appear to falter because of poor communication or because a new partner - either for DC or parents - alters the dynamic and causes tension.
There are also a lot of tales about DC who are greedy and grasping, take their DP for granted and have an eye on the main chance when it comes to inheritance. One point which keeps coming up is whether or not an estranged adult DC should inherit anything at all.
I don't have any answers but I do find it interesting to see another perspective. With some of the GNs, I feel like shaking them and saying get a life, be there for your adult DC, but don't interfere. Likewise on here, some of the posters appear to be self indulgent and petty in relationships, and there are lots of power struggles going on between MILs and DILs in particular. A bit more tolerance and mutual respect with better communication would probably help in a lot of the scenarios.
All part of Life's rich tapestry, I suppose! And definitely worth a read just to see another viewpoint (even if you don't agree with it!).
