The mutual friend of the toxic person I am avoiding is asking to hang out during the Holidays. There were a couple of times in the past year that we hung out, that the toxic person tagged along.

The mutual friend does not know I started avoiding the toxic person this year since she (the mutual friend) moved. She doesn't think it's any problem for us to all hang out together, when she is in town. I feel it's not my place to tell her of the toxic person's character, and I want to avoid drama as much as possible.

How can I hang out with just the mutual friend when she is town, without having to mention the toxic person?
