But unfortunately there are so few couples that love each other and have tender relationships in the declining years!
I appreciate your wish and hope you'll find the person to love him forever!
4 It' s wonderful to have warm and tender relationships when you are old, and moreover continue to love each othe, IMHO it's pinnacle of people's desires
1 It's good that you want to carry your relationship through your whole life. I also dream of somebody whom I would love till death do us part.
