Just because your Mum is 70 and you think she has everything she wants or needs, doesn't mean she may not like some kind of luxury.
I adore handbags and can't ever imagine not being pleased to receive one. What is your Mum's vice???
A weekend away at a luxury hotel?
Some luxury sheepskin slippers, fab jamas and gorgeous dressing gown?
A voucher to get hair done for a year?
New walking boots?
A few pairs of cashmere socks?
What are her favourite films of old? Get them on Amazon on DVD.
Does she have a favourite cafe/restaurant? A tab behind the "bar" for the next few months.
What is her favourite perfume? get her the perfume and the body lotion.
Gardening vouchers?
Is there anything she wishes she had done? (sky diving, sailing etc), books some lessons.
I really hope when I'm 70 I am still seen as a woman, and not just an OAP who has everything.
HTH.
