It was ever thus informal
A humorous way of of saying things are always this way or something has always been this way
Twas ever thus, on the first page of our life's story, everything seems so bright.
Everyone gets married and has babies when they grow up. It was ever thus.
To not react or deal with something that is wrong or unpleasant
Unchanged, be stable.
To be very wet
Because of forgetting bringing an umbrella, I look like a drowned rat when it rains.
