Let us assume that Liz lied on Day one, and told the truth on Day 2. Then, it follows that Day 2 is Thursday and Day one is Wednesday.
Let us assume that, Liz told the truth on Day 1 and she lied on Day 2. Then, it follows that: day one is on Tuesday and Day 2 on Wednesday.
Consequently, on a Wednesday -  Liz always tells a lie, because its her lying day.
