Do you smile when you make eye contact with someone at the gym? Or do you just give a blank stare and look away?

I just got done with a workout and this question came up in my mind and I wanted to ask you guys.

For me, I guess it depends on the gender. I’m a big smiler. I smile a lot. It’s weird if I don’t when someone looks at me because I don’t want to come off mean. However, I am married and don’t want to give anyone the wrong impression. The last time I did smile at a guy, he basically tried talking to me at the gym everyday since then. I told my husband this and he said “see that’s where you went wrong. No eye contact. No smiling”.

Idk what are your thoughts? Do you just walk around all mean faced? 😑😠
