The use of "Regret"

[Belles1654]

Can you say to someone, "I regret that you can't attend the event". I thought "regret" could only be used if you were ashamed or disappointed in the effect of your own actions. Thanks in Advance.

You're right. "Regret" is usually used in regard to one's own actions, but sometimes it can be used with things one has no control over, such as when someone regrets the passing of his youth.
