There are many nice things that you can do for your anniversary.
From buying flowers to going out for a nice dinner, you can never be too thoughtful when celebrating. Your significant other will appreciate some heartfelt words from you that reflect on your relationship and your anniversary.
You are my best friend, my lover, and someone I am happy to be stuck with for the rest of my life.
Your kiss is sweeter than honey, your smile is brighter than the sun, you smell more fragrant than any flower, and your voice is more melodious than the birds that sing in the morning.
I am so happy that we found each other and have not lost each other in the process.
This will especially mean a lot to the couple if they are your parents or a couple that you are close to.
If you admire them as a couple, then they might be flattered to hear that coming from you.
