Why does the word 'Cliquey' constantly pop up only on things about school mams?
There is NOTHING 'cliquey' about school mams and I have 3 kids and have been doing runs over a decade.
There are simply people who know each other and are friends, people who have great social skills and can engage anyone and people who do not have existing links and outgoing personalities. Like any other walk of life.
If you pop in boots and are standing in the queue and 2 women in front of you are chatting about one of their boyfriends new promotion are they being 'cliquey' for not including you? or are they just strangers going about daily tasks that you are eavesdropping on then for some reason taking their friendship personally like a bloody weirdo.
If you want to make friends actually make a proper effort to make friends (thats not just a smile or 'Hi' on the playground). Some people are good at that, some are not (I am not myself, I have learning issue that effect social abilities) but its no one else's fault you haven't figured out social skills to make friendships yet. Its not their job to read your mind and make all the moves to become friends with you and its not personal if they have other friends.
I think these threads themselves speak to a fault in social skills though. By the time you have school age kids you should be over that 'clingy' stage where you think someone has to be yours and only your friend. Getting jealous because the girl that said 'hi' to you yesterday is talking to someone else is very immature (toddler level social interaction) as is calling them names and 'falling out' and 'cutting them off' due to it is also immature (teen level emotional response).
Which is probably why people who start these thread struggle to make friends, a little self growth might help (or just be like me and learn to be a content loner because you know you can't control your neurodivergancies and strange find that weird)
