What do you call a person who is nosy, and observant but sometimes doesn't pay attention

Answer 1

A person who is nosy and observant but sometimes doesn't pay attention could be described as "inquisitive" or "interested," but also somewhat "scatterbrained" or "distracted." You might refer to them as a "curious but inattentive" individual. This combination of traits suggests they have a tendency to be involved in others' affairs while occasionally missing details.
