I see that a link between these above posts on this thread is that they are to do with tackling something which has been long awaited and also dreaded,
Another connection between many posts is the subtext of negative emotions (anger, contempt, disappointment, frustration) which Gransnet posters feel towards spouses who refuse to grow up and similarly rid themselves of their own real and emotional lumber. Men seem to be more self indulgent and immature when it comes to 'moving on'. They prioritise their lumber over that of their wives' possessions. It is also clear from reading some comments and posts that many men use their 'stuff' to control and vex their wives.
My husband has seventeen pairs of shoes under his side of the bed, many unworn for years. He has also kept his father's huge tool chest of drawers in the way in our garage when the man died decades ago.
I try not to get too angry with him and to ignore it. He has tried me sorely on occasions, for instance, when he used to take things out of the bin ( used milk cartons etc.) which I put in. I did object about that and now, if he still does it I am not aware of it.
I suppose the anger comes from the underlying supposition that, if it's virtuous to have a clear out, then it is 'bad' to hoard and clutter.
It is a strange psychological phenomenum that we attach moral significance to domestic tasks is it not?
