A card from my mum's trip to Budapest
As I remember (and the date proves me right) she went there with her colleagues in March regarding "Women's Day". Yup, travel agent's always find appropriate or inappropriate reasons to organize some kind of a trip, in order to empty people's wallets...
the card on the back says: "this is so you are delighted when you take a peek in the mailbox"
i think my mum is the person who best knew even back then, how i feel when i find something in the mailbox for me...cant say anything else, but an enormous "Thank You Mum"!
