Good Fortune

Completely confused.
Yesterday, I received an email and a notification from Blipfoto to say I had posted Blip number 1500.
My account says I had posted 1499.
I am marking today as Blip 1500 in order to gratuitously post a Blip of my beautiful daughter and our dogs.
She elected to accompany me today and was lovely company to walk with.
The dogs seemed to enjoy it too.
She did head home at the 3 mile mark and left me to clock up another couple of miles.
That takes me to 90 miles in May and almost 600 miles in 2020.

Edit: Blipfoto now tells me I have 1501 entries. I give up!
