My son was invited to a party. First party invite in years. It was fir a child a few years younger than him. He has many diagnoses and has learning difficulties, severe autism.... he understood that he was going to a party and was excited to go. We turned up, went into be told that he hand to stand against a sign (not a height sign, a please do not run sign), he was a cm over, one lousy cm. They wouldn't let him in, they offered to put some balls on a table for him so he could watch the others play. We left, he was so upset it was awful. He didn't understand why we left, he doesn't have that level of understanding. He was heart broken. I'm heartbroken for him. No AIBU really, I'm just venting and looking for opinions. They could have let him in couldn't they.
