People tend to ignore messages when they're caught up with something else, like being at work, in class, or even driving. Sometimes, they see the message but get distracted and simply forget to reply. If they're dealing with something urgent or stressful, responding to messages might not be their top priority, so they just leave it for later or forget altogether.
人们在忙其他事情时,比如在工作、上课甚至开车时,往往会忽略消息。有时,他们看到了消息,但被分散了注意力,干脆忘了回复。如果他们正处理紧急或有压力的事情,回复消息可能不是他们的首要任务,所以他们会把它留到以后,或者干脆忘记了。
