On facebook, would you delete a friend for inviting you to a group without your permission?

[Lindsay S]

If a friend of yours invited you to join a group you had no interest in joining, and did so without asking your permission would you delete them?

Do you feel it is always necessary to get a friends permission before inviting them to join a group?

[Corz]

why would you delete them? you get the choice to decline. Its not like they knew you weren't interested.

I don't invite people to groups at all.
