Complications? Light hearted

DD3's ex husband (aka The Arsenal or The Idiot!) recently had a bad time as his dad was in hospital with complications.

As none of us can bear to talk to him unless it's vital, we dont know what the 'complications' related to but have had a great time guessing.

And, if we just feel like sitting down and doing nothing we cite 'complications' as the reason.

Have any of you had complications?
