I want an innovative and an unique idea for my mother's birthday?

My mother is turing 45 on the 2nd of december.....she is a housewife,doesn't have any specific interests and doesn't really like celebrating her birthday(like most of the adults)...i don't have the guts to say i love you mommy and all that all of a sudden on he birthday(because i am normally not so emotional with her...i talk to her more like a friend)...so please don't give that sort of ideas...i want to make her happy somehow atleast on her birthday because i feel that her life has become quite dull due to a lot of reasons(one of which is our family not being able to live together for quite some time...because we are busy with school,college and job)...a family get-together is also not possible....only me and my dad is going to be there....and in the worse case it would be me alone...i am 16 years old...i can play and sing with guitar quite well and i am quite good with computers.
