when did you sing to someone

i hasn`t sing to someone because i am very shy  and i dont like to sing because i dont know how to sing.And i am shy because what if they sayd me that song is boring. so for that i prefare to dont do nothing.
i think one time but i gat back because se¡he loves other.i dont think to dedicate a song is usefull because i prefare to be a good friend.but i sing a song in the happy birthdays and then i give she or he a hug and  give he/she te present.
