The question frequently posed by many is "what and how did you realize or get this understanding?". Firstly, remember that you are trying to find your own Self. The equipment or instruments of manifestation of the ONE are many. Each manifested entity has its own set of attributes. Based on its attributes, each manifested instrument will experience the same object differently. Therefore, when one "experiences" the Truth, it is likely to be different from another one "experiencing' the same Truth. Therefore, do not worry about what" experience" or absence of experience another person had. Just worry about your own self. First, with single mindedness, investigate who you are, before you question about anybody else. (Explanation: Because of difficulties of expression in words, the liberty of using words in different manner has been taken here. Despite that, hopefully the message gets through).
When one expects one who has realized to behave in a particular manner, it contradicts the very notion of perfect freedom. Freedom from predictability. Again, behaviour is based on the combination of the basic three attributes (sattva, tamas, and rajas). The realized one knows for sure that he/she is neither the body nor the mind and is oblivious to the actions of the body-mind. In the Absolute state, nothing has ever happened. All happening is in the realm of consciousness. The Absolute is prior to consciousness.
