One of the good things about getting older is people are more forgiving of eccentricities and individual quirks in behaviour.
Obviously as we get older we learn to adapt and mimic NT behaviour - it's normal to mirror behaviour we observe, that's how we learned to walk, talk, and do everything.
It's fine to do that if it helps you get along with others, and doesn't make you feel fake, inauthentic, or otherwise grate with you.
If it does, then you need to weigh up and decide if it's worth it for you.
The problem I faced, is that I was one of the "invisible aspies" - I'd learned only too well how to mimic NT behaviour to the point that numerous doctors, psychologists and others either thought I wasn't on the spectrum, or thought my symptoms were so mild that it didn't warrant diagnosis.
Obviously there is a huge difference between the way we act and the way we feel; that's why so many great actors are aspies; we literally learn how to "act normal" so that we reduce the incidents of being ostracised, bullied, belittled, and abused.
So it's not wrong, and if it helps make your life easier go for it.
Just remember try as we might some of us can only fake it so much, and will always seem odd and have others pick that we are different.
That's when it becomes a judgment call; if someone spots that you're different and you have been diagnosed, you need to decide; does this person need or deserve to know my condition, and what is the likely outcome?
Some are fine if you say you're an aspie, some will not get it, and some will think you're looking for a convenient label to make your odd behaviour acceptable.
Be yourself, learn to accept yourself, and if part of that is acting NT, and you can get away with it good luck to you.
I'm just not so fortunate, and sometimes wish I was.
