At least if you gift a SP something, she truly exists and will thank you in person
I think there are much better ways to find out if she truly exists and I will thank her.
I don’t mind them having a wish list at least if I want to buy her a gift I know what she would like and what her tastes are.
I have bought many different things for ladies I have been seeing for many years. For ones I see only a couple of times it is just wine, flowers, pastries and chocolates.
