what you see may not be what you get

oh gosh. i begin to worry about my 21st.
was booking the chalet a wrong move?
i'm afraid there wont be enough space for all my guests.
i came up with a rough guest list and goodness! THIRTY OVER!
and i havent added in my relatives which is not gonna be just a few.
oh no! oh no!
mother was telling me to celebrate with relatives on sat (28th) at home, but then, it'll be after my actual birthdate so... i dont like that idea.
i still hope to have everyone on the same day so that they can see what i have planned (ok, not like something very grand but at least the 'atmosphere will be there right?)
oh gosh...
i hope i can settle the space problem..!!!!
do someone have any good advice?
i think i am over-stressing bout this whole 21st celebration. am i?
