Garden Visitor

I have no idea what this plant is but it is very pretty. It suddenly appeared in our drive way and conveniently up against the fence. It's a couple of feet tall and has very dainty flowers. Maybe some sort of Veronica but there are so many of them that I cant find any like this after a quick google search.

I've been feeling very tired and listless the last couple of days. I think being at home all the time is getting to me. We did manage a 3/4 hour walk this afternoon.

Update with thanks to ex-blipper DevonDumpling: It’s the pink version of Linaria (Toadflax)
