Hi SS friend'sIve read somewhere that demons would take something from us for the helps and favours we ask them to do for us. But Im concerned what they could be taking from us. Could it be anything that affect us badly? or something that we don't want to let go from us? Ive been bothered about...

HI all, I've been experiencing a demon presence around me. The demon has rescued me from a trouble I had,  I wanna summon this demon.So what kind of offerings does a demon accept? How do I know the demon has agreed to accept my offering? Please give me some knowledge about his.Thanks,HAIL SATAN!
