Feeling Lethargic

It's SO HOT today!! It reached 37.9C (100F) not long ago and its still very hot now. I know I am meant to do my UV today but I honestly don't feel like it. Yes I KNOW I could've done it earlier today but it was really cool this morning and then since it's Friday I go and do the weekly school newsletter at the primary school. I can just hear the voices of Mark & Diva saying you NEED to do this!! Maybe once the sun has gone down.. .. ..
