The past(Will you marry me in future?)...

I opened the note to read and it was as follows:

Note: Don't smile or laugh looking at all this, first thing there's no birthday party we both are arranging in surprise 'Cause we know you hate birthday parties and your weird boyfriend feels the same. Second I'm sorry for leaving without informing I know you would be worried.

 You probably know I'm not at my uncle's house and thanks for not calling. Now take a bath, wear these clothes, don't tie your hair, drive your motorbike, and come to the cafe, why bath? because I don't want to smell the sweat. We all three will have dinner here. Your boyfriend said he's good at cooking so we've to eat that food.

 You know the day we both went out to buy these clothes, we both selected the same thing. I hate that Patrick knows about you as much as I do but I was a step higher than him cos I'm the only one who knew your clothes size. Come to the cafe by 7:30 and don't be late.
