Hi everyone, does anyone have any suggestions for a working to keep someone out of a space or area? Sort of like a "reject all access" lately I keep getting interrupted during workings, thankfully I had gotten very far when this happens. But I have asked this person and I don't think they're intentionally interupting me, but since I can't really say "im trying to cast a spell, can you please not interupt me" without being called crazy or the like. I do have protection spells and what I call privacy spells but I think I need something more.

Thank you in advance for the help.
