I once bought my sister-in-law a lush bathbomb set. Forgetting that she only had a walk in shower.
Weirdest gift i received- I was extremely drunk one night, got a taxi home and was talking so much pish on the way home. Before leaving the car, the driver handed me a book and said "I think you will find this very helpful". I just took the book without looking, went into the house and passed out. I was wakened up by my ex demanding to know why i had brought home a book in Scientology! I gave up the drink for 6 months after that!
