There is something that jumps out at me from this thread.
The adults who were the 'lonely kids' at school don't appear to think that the solution is to 'be inclusive' or to 'be kind'.
And there are only a few posters who point out that its the academic kids who are often the lonely kids.
My experience of school was i didn't fit in anywhere. I could get along reasonably with everyone but i wasn't part of their social group and both parties knew it.
That was a far more lonely feeling than days when i managed to go to the library and just read a book or do some homework. I'd much have preferred that.
I was academic and that didn't help. I wasn't so much actively bullied to a great level until I was about 16 when one girl tried to ostracise me from a whole group and made life uncomfortable for them if they were nice to me.
I also was saddled with a disabled girl in class by one particular teacher to 'be kind'. She was in mainstream school and was capable of doing everything if she tried but most of the time she preferred to get certain people to do things for her when she could get away with it. She started to insist i did her work for her in this one case (in addition to my work) 'because she couldn't write'. Something she miraculously could do in every other class. She was really manipulative and nasty about it. In the end my Mum complained about how she was treating me and I was the one who got hauled in by the teachers over my behaviour. I still to this day maintain that it wasn't my responsibility to do her work as well as mine and if she needed that level of support it should have been provided by school. I definitely shouldn't have had to put up with the abuse her and her best friend gave me over it. (She left school at 16 in the end and had a baby by the time she was 17 ironically). I was told I had to be kind (I'd been given the task because I was bright and conscious in the first place!) but it definitely was at my expense and i was taken advantage of.
Honestly i swear there is a complete disconnect with reality going on here.
I want my son to be more popular than i was, but I still want him to be academic because he has to compete with everyone for a job at some point. I want him to be a nice kid who knows when someone is taking the piss and taking advantage of that generousity of spirit.
Its a balancing act. Its too easy to say 'well just be nice' when there are others who are happy to trample all over you, the second you give that inch. Its far better to teach kids to be emotionally and practically self sufficient in some areas.
Equally i do think theres a lot of kids who are in social groups who think the stigma of being alone is justification for never challenging the shit behaviour of others (when they themselves havent been involved) so effectively turn a blink eye rather than doing the right thing.
The most i think about that meme the more i think of how far it misses the matk, doesn't understand problems and almost places blame and perpetuates the stigma and stereotypes of being the lonely kid or the academic kid rather than helps it.
It reinforces the idea that its bad to be on your own and that its bad to be academic. Its completely contrary to what those two groups who are at the bottom of the universal school pecking order (which is the same pattern seen throughout the world regardless of culture) in the first place.
Maybe we should start by looking at why what that hierarchy is and why it exists and structurally analysing where its coming from rather than putting virtue signalling meaningless memes on social media which we think make us look good but actually are worse than useless and become part of the problem.
