That seems an accurate description on my fake smiles lolI assumed it was real because I don't recall him ever having an open-mouthed smile in any picture he has posted and when I'm doing the nearest thing to a fake smile I can do, it's close-mouthed.
Honestly, though, I don't understand how people can do fake smiles. If I'm pissed/sad/annoyed, I cannot fake a smile for the life of me. They may be uncomfortable smiles or I may be smiling at the running commentary in my head if it's a situation I really don't want to be smiling at but I can't fake them. The best I can typically scrounge up is a corner-twitch and even that tends to lead to a real smile because I feel like an ass for thinking I can fake it.
[/overly long thoughts on fake vs. real smiling]
Only i don't smile even when i am in good mood. A little thing i am proud of is my fake annoyed face.
I guess imo a face should reflect the state you want others to think you are at, instead of the actual state you are at. You can't give people too many clues into yourself lol.
