I’d suggest that we avoid telling any scary story stories with Janet around. She’ a bit unstable

It is no fun to tell frightening stories to Janet, who is not very stable mentally, because she only laughs instead of getting scared.

Janet has trouble keeping her emtions under control, especially when she is told frightening stories.

Since Janet is somewhat unbalanced, the only way to make her laugh is by telling stories, but we should avoid scary ones as they might cause her to panic.

Janet is somewhat mentally unbalanced and might easily become uncontrollably emotional, so let’s not tell frightening stories in her presence.
