I don't think it's like a feminine thing, I just think smiling conveys that you feel happy about life, and people just like to see you happy. I went years without being able to smile. I mean I could screw my lips up into a curve but my eyes belied my smiling lips and betrayed the sadness within. I don't think it looks bad to look contemplative or anything. I want you to be happy and love life and all of that so I just wish I saw more happiness in your eyes Virginia, you look like you are hanging out somewhere behind them.
I dunno how many hundreds of times I've been told I should smile more in my life, but I can say for sure it wasn't because any of those people wanted me to look more feminine. ...lol. Now it comes much easier to smile, and I'm glad.
