Sweet birthday surprise

My sister planned a birthday surprise for me this year and it was a success! Cos I did not have the faintest idea until I saw them at my place. Of course this was made possible with a good accomplice: JQ. JQ and I were out till about 9+ on my birthday. When we reached home, I saw him opening the shoe cabinet with the intention of keeping his shoes, BUT he took out his shoes and left it on the floor. I asked him what he's doing, and he said he wanted to air his shoes. DUH! I did not suspect that there was no space to put his own shoes. Next, I was babbling nonense to him in the kitchen. Usually, I will head straight to our wardrobe room to change out first and that's where my sis was hiding. So he had to lure me to our wardrobe room from the kitchen, wondering why I did not follow my usual routine this time. And there was my sister hiding in the wardrobe room with a birthday cake. BOY was I shocked. My next question was eh, only you ah? Mom never come? I turned around to see my Mom sneaking up behind me with a sheepish cute look on her face. You really should see her face, she looked like a small cheeky naughty girl so much so that I wanted to pinch her cheeks! So I was really really surprised, and touched this birthday. If you are wondering what happened to my Dad, well, he is just not into this kind of family gatherings. If it's proper dinner with table setting, he will be there. =) Anyone has any ideas how I can get my Dad to be more involved?
