WAS THIS TOO FOWARD OF ME OR JUST RIGHT? THANKS

well I seen the bus driver I have a crush on who I think is about 36, I am 33. he is always shy but extra nice towards me and talks very low and mild mannered….so as I am getting on the bus today, he just cheeses and grins with all 32 teeth and says awww u shouldn’t have n proceeded to ask me was that package I had for him, I said no this is mine all giddy and he laughed and I said my boss gave this 2 me as a gift…all the folks on the bus just lol and smiled at the two of us and the bus driver said congrats and I said thanks, and as I was about 2 get off the bus he just kept staring at me and smiling and said loudly/confidently for the first time ever have a great day while still smiling. i proceeded to say thanks and i asked will you be driving again next week, he said yes smiling. i said ill bring you a Christmas card he said okay, okay extra happy smiling with all 32 teeth showing…i was wondering what could i write in the card that’ll grasp his attention
and let him know i wouldn’t mind getting to know him outside of the bus route…..I think there is a mutual attraction here. I was thinking of writing in a Christmas card, me and you coffee ? (im not a coffee drinker but I don't mind trying something diff) and write down my name and number and leave the rest up to him…or is that too much?
thanks for any answers
