8-(...Those aliens tend to abduct the wrong people. ;-)
My cat-killer has the following first statement about that:
jealous
Feeling resentment against a person
because of his rivalry, success, or advantages.
(Apart from that the word was used the way I was taught about it in
school.)
The first two translations given in my dictionary were:
eifersuechtig, neidisch.
(Usually referring to wanting something someone else has;
according emotions tending to be implied as lacking wisdom.)
