My grandpa had a gift for people - the man could start a conversation with anyone, form fast friends and remember their spouse’s middle name in twenty years.

As he put it, it’s a coin toss. Maybe you’re bothering them or maybe they’re grateful to have someone to distract them. Each is equally true before you start the conversation.

The key is being able to read social cues. If you can, you can stop bothering them.
