I am extremely sentimental, but this is not directed to or merely in relation to material things, they are only a proxy, symbols for what I associate with them. Much of my sentimentality is not associated with tangible objects but gestures within the realm of all senses and modalities (emotional, cognitive...). This is because things (in the abstract, not literal) really matter to me in the quiet circles of my heart. I suppose nobody could accuse me of being shallow. Ironically enough, this character trait of mine also spells my doom. Life is Théâtre de l'Absurde.
And I should also point out that it is also subject to variables. When someone gives me a gift and it's clearly an insincere token, I attach no significance to it, I can be polite. Yet I am that type of person who, when given a freshly plucked dandelion half already gone to seed, from someone who genuinely values me, I treasure it. Or even a look, or a word. A gesture. There are no boundaries in that respect. I can relate to Judge, too, in a way, as sometimes I am so overcome by the meaning of even the simplest things, that I can't express my feelings in the moment. That's often gone over like a lead balloon, I tend to ruin special moments as my silence or stammering or whatever is oft misinterpreted and perceived in the most negative of lights.
Essentially what I'm trying to say is, I'm probably bloody impossible. But very sentimental at it.
