Yes, in addition the tradition also comes from my grandparents, imagine then how far the tradition has gone, but not only in my family, in almost all Spanish families it is usually played at least once a year and that is the Christmas lottery, the prizes are substantial, but the possibilities are tiny.I actually figured it might be as a result of tradition that you kept doing this and it's also the same thing for your family members because traditions are always very hard for people to break especially when it is something they have been practicing for decades.
