I am not sure what is normal, sending a mail by post is not
normal these days, with sms, whatsapp, skype.....
but when i sent greeting cards, birthday cards, christmas cards,
...sent before 5 pm, the other sides received the next day, or when
they open their letter boxes, so far so good, not sure if I want to
continue to count on the service of regular post, because that is
not their main business anymore.
