Hoooo boy, I've probably got a lot of these!
The first that come to mind is how I have quite a bunch of weird, pretty specific eating habits? I think they mostly stem from the fact that I'll often try to finish with the part I like the most, so it leads into stuff like cutting out the middle of breaded fish so I can eat it first xD
There's also this specific type of small circular chocolate cake we get that I love, and it's got "eat warm" written on the cap… but when I was younger, after having eaten it warm only once or twice, I tried it cold straight from the fridge to go faster and just, kept doing it? So in the end I liked it better cold than warm xD (and I still do)
Another one, still kinda food-related: one time, when I was younger, my mom showed me on to put my napkin on my knees before eating (we have nice ones with fruits embroidered in a corner). She put it on my knees with the corner with the fruit being up-right, and she told me something like "This is how you place it". Apparently, my brain interpreted that as "the fruit must
always be in the up-right corner"! So even now, I keep that fruit there when placing my napkin on my knees, and when I use another type of napkin (without fruits) I put the label there instead xD At least it helps me keep always the same side of the napkin up.
…oh and i keep eating the "dead" skin of my lips i should really stop doing that oops
i pretend to look at other people when theyre talking because i cant stand eye contact but ppl get mad if i dont look at them so i usually try to make it look like im looking at them but actually i'm looking at somethng behind them or something.
i feel you! sometimes i've tried looking at their nose instead of their eyes, i think it helps since it's so close to the eyes that people probably don't notice, but it's technically not the eyes
