Humm regrets can't say I have any..Yes, I have made many mistakes in my life and learned from them, some I made more than once.

Only thing I can say I wish I had spent even more time with my Granny just talking~~

Even if you technically could have done better, you likely could not actually.

A relationship can be even better if they realize you are not perfect -and that you love them so much you have such regrets -wanting to go back and do things perfectly. Then they will also know you better rather than trying to maintain an illusion of perfection or invulnerability.

Discussing regrets -which means having them in the first place -is a great opportunity to increase closeness, trust, etc.....
