My Father

well, i heven't talked too much about my father, not because i don't love him or any reasons but i don't know how to say something about him..

today when i came home after work in the restaurant, he gave me some money in secret and said 'you're an adult & you're supposed to leave some money just in case;i don't have much money to give you, so don't spend all of it.' i didn't say anything even a 'thank you'.. i don't know what should i say..

my father always gives me money in secret. i know he loves me; however, i don't really know how to react, maybe just because chinese culture; i wish i could say something to him..
