Indifferent means not caring either way. The shrug when somebody asks which restaurant.
It takes to: indifferent to criticism, indifferent to the cold. Applied to somebody's attitude it can be damning, since being indifferent to suffering is worse than disliking it. There is a second sense that catches learners out completely, because indifferent can also mean merely mediocre — an indifferent meal, an indifferent performance — with nobody's feelings involved at all. The noun is indifference, and a matter of indifference means it makes no difference to me.
