Always listen for things that your partner reminisces about and jot them down
somewhere. For example, perhaps she talks about the ice cream that she had
from a particular shop when she was a little girl.
When a special occasion comes along, check your list of things that your
partner talks about and try to recreate one of them, for example, visit the
shop and buy a tub of ice cream making sure that the name of the shop is on
the container.
