To answer the question no I don't worry about Friday the 13th.
However, did anyone think it was unusual that we had two months in a row with a Friday the 13th? The thirteenth was on a Friday in February and in March this year. I wondered what the odds were of that happening in successive months.
My daughter just got all her bad luck out of the way early this year. Yesterday she fell off the bar stool at her dad's shop twice (mostly because she is 9 and going through a growth spurt, so her brain isn't sure where her hands and feet end right now). Later in the evening she decided to move the television to a better angle for viewing from her chosen seat and managed to pull it down on top of her, bruising the back of her hand and wrist. She says her face feels bruised today, but there is no visual evidence of it.
