Take working fairy lights and large Xmas tree. Add long and drawn out struggle (solo of course as everyone else “busy”) to unite the two involving having to remove leopard print onesie (birthday present) half way through, as getting too bloody hot, and finish job in underwear. Step back to see tree artfully festooned in now completely and stubbornly non operational lights and transform into angry, homicidal, wild haired, middle aged woman. Add chortling husband and kids taking sneaky photos from upstairs, to complete a total loss of sense of humour. Send everyone to bed. Add huff-induced glass(es) of wine and marinate. See funny side.
