Hello gallant, while reading your lines, I felt that many of them were written by me, besides you made me feel that I am not the only one who loves to be alone, the only ones I accept in those moments if I am at home with happiness, is my cats.
I also pretend dementia and I pretend I didn't see people, to get away and like you many times it doesn't work for me, but then I remember that if they have approached me it's because they appreciate me so I try to see it from another point of view, although there are days when you just don't want anyone by your side, even if they love you and vice versa, I love when I am alone at home and I have my moments of solitude and inner peace, as the master Oogway from Kung Fu Panda says when finally everyone leaves and leave him alone, hahaha.
PS: I thought I would read something related to coffee and yes there was, but you were interrupted in your moment of enjoyment.
I believe it's wise to be able to find moments of value no matter where one is, even when surrounded by others. It's a state of mind I guess. I find many such moments in my life but sometimes feel like creating them and often that means excluding other people from my immediate proximity.
Thanks for your comment.
