My friends, wishing you all the joy that your heart can hold and may this be the new beginning of a long life together. Tons of good wishes on your engagement!
The road ahead will not be as smooth as silk, but with the right person by your side, you will get through any challenge. Congratulations to both of you!
Technically and traditionally, engagement is known as the promise to marry. But practically, it is known as the promise and first step to lifelong slavery. Carry on!
