Need some time

My friend called me through few minutes back .he asked me to be ready so that he will pick me on his way . Don’t know the reason but I guess my friend is taking me for a movie. I want to inform him that I need thirty minutes time for me to get ready. Yes I have applied oil on my head and I need time for me to take bath. Don't know the reason and I have dandruff for few days. With the help of hair oil it will be possible for me to get rid of the dandruff.
