It sounds like you may be a really likeable person.
The way some people are wired they need human connection way more frequently.
See the situation as a positive thing and go easy on them.
Don’t waste their time either and wait half a conversation for them to pick up on hints. An immediate and considerate, “Sorry really busy right now, you’re kinda interrupting my flow – please let me get back to you later,” can go a long way.
