At the risk of being rejected from the INTP collective, I am wondering about how my propensity for occasional sentimentality can be rationalized. I'm not ridiculously sentimental, but I like certain very emotionally meaningful keepsakes, particularly of relationships. For example I've kept souvenirs of my first date with my partner, and can not throw away a broken woven anklet given to me by my partner that can't be repaired or worn again.
On the other hand I have never been one to keep track of or display things like sentimental photos.
I do enjoy keeping track of and celebrating certain personal observances like anniversaries. Holidays, on the other had, mean nothing to me.
So, I suppose I'm just wondering how to rationalize sentimentality in a Ti-Ne framework and wondering where other INTPs fall in terms of sentimentality, especially with respect to objects or observances like anniversaries, etc.
