What is sarcy lol?
I dont think the bf or even mixed beauty thought the birthday is president’s birthday. 
We dont bother about presidents’ birthdays, do we? You are just putting arguments for the sake of it. You see, you set you priorities. You get that feeling from within to celebrate your loved one’s birthday. Its more interpersonal specially in this case and your absense will be felt. Whats dholki on the other hand? Just sit there, sing, clap? Even if a pair of hands is missing, it isnt that big a deal. NO?
