while I am doing something -- inability to switch attention to someone speaking to me if they do not first ask for my attention (excuse me / hello / myname / cough / knock) before diving into speaking in sentences.

very often by the time i start paying attention to them speaking -- they are 4-5 words into their sentence and I have missed the context of what they are talking about and i have to ask them to stop and repeat from start

This has happened with me in multiple settings (work and personal life)

Not sure if this is a common thing along with APD - which i recognize some symptoms of in myself
