If you left on good terms with your former employer I see no reason why you shouldn't try to return. Although there are some organizations that have a policy not to re-hire former employee's. If you are still friends with anyone at this organization I would try to find out if such a policy exist first or simply find out has anyone ever left and returned.I recently changed jobs.

It never hurts to ask. Tell your former boss that you made a mistake and would really like to come back to work there. The worst that could happen is that they say ';no';.
