How odd!
Odd that some don't get that even in a long term relationship there is still individuality. Me and Him. Different people.
He has his clothes, I have mine. Same with laptops, favoured cups, all sorts of stuff.
Then there are the things that are MINE! I chose them, bought them, received them as gifts. If he was to remove them he would have a lot of explaining to do. He too has things that are indisputably HIS.
And then there are things that belong to the HOUSE and neither of us should deprive the other of the use if them. The stovetop mokka, the knife block, the yellow plastic thing that makes taking lids off easy, the indoor toolbox, the outdoor toolbox and all the contents, the pasting table and on and on and on.
Stuff we both use with more or less regularity. The stuff that is always there, to be used, that simply is.
Neither of us has the right to remove such stuff without agreement, because such stuff is what makes the house run properly, what helps make it ours - not someone elses, a way to make a mate happy, or just a simple way to solve an immediate problem - then to be forgotten, whatever!
