It's okay to say you are busy when you are having your time for yourself. When you make coffee for yourself, when you sit in the balcony and read books, when you crash on the bed and watch cartoons, when you make your home beautiful, when you sit idle doing nothing but contemplating on a rainy evening, when you sleep till the sun is above the roof after bathing you with the golden shines, when you just sleep on a lazy afternoons, when you take long showers at 10am singing out loud, when you go watch a play on a evening, middle of the week... It's okay, to say "I am busy". Having "Me Time" isn't less of a priority. There is much more to do in solitude than calling it as loneliness!
