Two people lost on a hillside

My little sister, Joanna
Is 44 years old today
Look at her! You wouldn’t guess
The wrinkles just stay away

A skincare routine that works
Definitely better than mine
I’m only 4 years older
And I’m in deep decline

Because having Jo for a sister
Sometimes causes me stress
Like the time I mistakenly licked
Milk expressed from her breast

Mentally scarred from that day
I’ve not been able to move along
A simple check of heated milk
That went all kinds of wrong

My sister of course laughed
Her very loud, contagious cackle
The decibels I’m unsure of
But the windows defo rattled

That’s Joanna allover
Forever daft and young
Whether gigging or climbing hills
We’re always having fun

So happy birthday Ickle Sis
Have a fun time by the coast
I hope you’re being spoiled
And your present’s in the post!
