You're getting better. Although I feel like I want to punch the Dad for being too clueless at times.
Much better than the second one, which was terrible the moment it said "Oh she has a headache" I groaned as I knew it was gonna suck. Then the bit about going in his room - Ooh I wonder what was going to happen there. Was disappointed at the end though, I thought Dad was going to ring back against the background of things being thrown around etc saying that Mum had gone crazy. Instead we got a coma, felt like a cop out.
Watch your voice as well. You keep it well when you're trying for "the lols" when introducing a new plot twist but you soon get too "Jamieson" towards the ends of sentences.
