paraobon

English: Translation
A person who habitually leaves or forgets things; one characterized by repeatedly failing to take belongings or companions along.
Notes

'paraobon (para- + obon)

This denotes a person characterized by repeatedly leaving things behind:

a habitual forgetter; one who habitually leaves or fails to bring belongings.

“Occupation” is theoretically possible with para- in appropriate roots, but leaving things behind is not normally an occupation. Here the natural reading is habitual or characteristic agent.
