Sometimes lunch can be a problem when other colleagues kindly invite you along and your buddies do not want to follow.
You have been working together with your colleagues for so long and it will not be nice to reject their kind offer. You love to mix around with all the kind souls.
You cannot leave your buddies for the other groups since it is not nice to do so because your buddies are the ones who are always there for you.
Will you abandon your buddies?
