It was DN's birthday a few days ago, she turned 12. I completely forgot to call her and wish her a happy birthday.
I did sent money to DSis for a gift (they live abroad) but on the day I was taking part in a sporting event and completely forgot about DN
. I have just realised what I have done when checking my bank account and seeing the bank transfer.
Unfortunately I have form for that. Despite putting reminders in my home and work calendars and on my phone, I regularly forget birthdays and anniversaries (including my own!)
I want to apologise to DN and DSis but I am worried they won't think I am sincere as it has happened before 
I feel like such a dick, and I don't know what to do or how to make it up to DN.
Any ideas please?
