My parents have a spoon that's shaped a bit like a cockle shell. I noticed this at 4 years old, and I remember my mother tempting me to eat things by offering it with "the shell spoon". I obliged when she did this, not because I was tempted by the shell spoon, but because it made me feel a certain way each time she offered. Not quite an appreciation of her thoughtfulness, but rather the dread of a tragic scenario in which she was unable to tempt me with an object she thought I liked. And the truth is that I didn't really like it. The edges of the shell were very sharp, so each mouthful felt like dragging two dull blades across my lips.
I would never let on that I didn't like the spoon, because I couldn't bear the thought of her feeling like she had failed me. The dreams in which my mother tried but failed to rescue me from various perilous situations were distressing enough. In my desperation to assure her that the ways she expressed love hadn't gone unnoticed, I did all sorts of things I didn't much want to, and feigned enthusiasm for things I considered banal.
To this day, when I open my parents' cutlery drawer and see that spoon, my heart sinks. No one will ever use it, I get sad every time I look at it, but I can't bear the thought of anyone throwing it away.
There is nothing emotionally healthy about the shell spoon.
Not to denigrate your experience but this is a good litmus test for anxiety. I can't relate to this at all but my partner is hyper-aware of the feelings of others and readily attaches emotional significance to objects so this anecdote is very much something I'd expect from her. I hope your day-to-day isn't filled with feigned enthusiasm.
My partner brough one spoon that doesn't match the rest of the silverware (provided by me). I initially wanted to say not to mix that in, but I kept quiet. It's just sitting there, laughing at me every time I open the drawer.
I avoid this by consistently using the same spoon. Other dishes may sit for awhile, but the chosen spoon gets washed after every use. Because there's not just one weird spoon. There's a whole stack of them and I have no idea where most of them came from. One of this, two of that, it's all hodgepodge chaos.
But I'm glad they're there. That way, my spouse has spoons to use that aren't the chosen spoon.
As is often the case, NTs will tend to have preferences here and relate, but the extent of discomfort at getting a weird spoon will usually be different. And it's hard to explain to an NT just how bad it is.
The bad spoons are useful for getting food out of jars or the like, so I don't have to eat with them! Also luckily twin likes the heavy forks, I like the light ones, and husband mostly does not care.
Hammer it flat and use it as a spreader for peanut butter and other spreadable items. Honestly, I find it superior to using a knife due to the wider surface area.
I scoop the spread with a tea spoon, scoop it from the spoon with the edge of the bread, then spread with the back of the spoon. Hate to do it differently.
I went ahead and exchanged our complete set of cutlery with one that I like and got a 12 person set. We are two people in this household. Nobody ever has to use the weird spoon.
