Like Valentine's Day - most weekends are days of love - all week is mostly business, career, work, money or profit - but on weekends people's hormones dance and loneliness starts to bother.
If however weekend is the only prime time you have to offer a girl - then you have far too little to offer. A girl wants to be loved each day - each hour of the day - eternally. Hence if you are properly prepared for a love romance - then go out on a Monday or Wednesday or any other day of the week and choose among those girls being free and available for love each day of your life.
