It's good to be concerned about someone's well being.
One of Sam's friends and colleagues, from work, has been sick with the flu for several weeks and hasn't been at work.
Sam needs to decide if he will check up on his friend.
Sam calls his friend to express his concern for his health and offers any support that he can provide.
Sam decides not to check in with his friend because, if he is sick, it may just be a bother to him.
Sam's friend feels good that he has friends who support him and the call brightens his day.
His colleague is hurt that Sam hasn't called or visited him over the time that he has been too sick to go to work.
