What is the difference between 'forget something' and 'forget about something'?

Off the top of my head I would say that a forget a thing but I forget about a process.
I forget about eating when I am busy at work.
If I forget my keys I will not be able to get in the building.
When I think of sports I always remember football and basketball but I sometimes forget hockey.

However, they may be others who can elucidate this more precisely.
