happy birthday to mom

It is my mother birthday and my father booked a birthday secrtly for my mom so as to give her a surprise,but my mother found the receipt in my father wallet so the surprise was broken.How sad for both of us.IOur plan is totally failed but pur birthday plan is still ready and I also wonder wether I give my mother gift or not.I am afraid that she might be angry to say that I waste money.I am looking forward to night of birthday.
