I have observed enough allistic communication to know that generally, if somebody points something out to you that you can already see or are already clearly interacting with, they are making an indirect request. but as I don't know what the request is, the only way forward is for me to guess (and likely get it wrong), or prompt the allistic to tell me clearly what they need.
however, allistics don't realize they do this, so asking them to say the unspoken surprises and confuses them. this is not their fault. allistics can be quite emotionally fragile and perceive directness as confrontation, so they habitually rely on indirect speech and coded language to preserve others' feelings. this is why they may find it difficult to be direct, even when asked. I have found that with enough gentle encouragement and reassurance that they are actually helping you, you too can achieve successful communication with your allistic friend or loved one. :)
