My first curse

Use a witch bottle I heard it turn negativity to the sender.

this is really a threat... call local authorities, magick might not work (backfire) and your chances are greater there for the safety of the elder. however binding and protection is smart too.

From my little experience I think you must have a good reason and engough hatred for a curse.Also,a good reason is necessary.

Personally,I don't believe in karma,three fold law or another things like that.I cursed once someone and nothing came back.However you are the only which can choose to believe in karma or not.

I suggest after you put a curse on someone to try to "forget" about it and don't be very excited to the results .

Be patient,is possible to take some time.
