very kind, generous
a heart of gold
helpful, well-behaved
as good as gold
no sympathy for others
as hard as nails
nuisance, difficult
a pain in the neck
irritates everybody
gets on everyone's nerves
refuse to think about a difficult situation in the hope you won't have to deal with it
to bury your head in the sand
bad memory
to have a head like a sieve
unaware of reality
to have your head in the clouds
very normal; no radical ideas
middle-of-the-road
thinks he knows everything
a know-all person
