Happy anniversary, Laura & Ark! I hope that you had a good one. I'm not usually one to quote biblical scripture (ever), but the following seems appropriate for this occasion:
Request and it shall be given to you.
Seek and you shall find.
Knock and it shall be opened for you.
For everyone who is requesting is obtaining,
and who is seeking is finding,
and to him who is knocking it shall be opened. (Matthew 7:7-8, Concordant version)
I feel it is a good recapitulation of your history as a couple, as well as your work together with the Cassiopaean experiment. Wishing you many more happy years together :)
