"Smile more then you won't look like you killed someone .Trust me 👌"

So this was said by a friend of mine which we don't really talk that much anymore . She told me this when I posted a selfie of mine on Snapchat about my new haircut .
First of all ,I can't be as dramatic as other ppl to smile even when I'm upset . It's not that I'm immature or I can't deal with shits around me, it's just that I'm not those drama queen you want me to be .
And smiling when you're selfie-ing is not really a must tho.
I'm not you . Maybe you smile in every of your selfie /photos but I'm not . And what's your business with me whether do I smile or not ?! Can't I just be who I am .I did not stop her from faking her own nice smile , why is she stopping me from expressing myself ? Pls don't force a person to smile when they're not in the mood to.forcing them to smile won't make them any much happier . In a way you're actually pressuring them . Do what you feel .why must I fake a smile when I'm not happy ? to entertain the people around me ? If you really do care about that particular person aren't you suppose to comfort them instead of asking them to fake a smile and entertain you with their smiley Lil face when deep down they're damn hurt ? Is it wrong to express yourself ?? Plus I don't need someone to teach me how to selfie lol HAHA HAHA
Moreover I did not ask for your opinion -,- not all models smile on every photoshoot they had pls (I'm not saying I'm a model here tho) Imo it's much better for you to express your feelings than faking a smile . Smile when you really feel like doing it . That's true happiness
ahh ... After expressing everything , I felt so relieve rn, thank you :D) and I just realise how childish I am haha making a big fuss just bcs someone ask me to smile :"D or else I'll be treated as a murder :"D
