The flirty thing could back fire 
Some girls like flirty guys 
Hmmmmmm…break-up techniques…well..
“Your mom doesn’t like our relationship anyways..so its best that we part ways..like this we will all be happy one day!”
well..my mummy daddy thing would never work with me..coz ppl who know me well know that I am a fighter and dnt bow down to any rules. So it has to be his mummy daddy for me
Yeaa…“I am taken already” works too…but some guys jst dnt give up 
Sometimes its difficult to turn down ppl you work with..coz u REALLY have to be diplomatic…its like walking on egg shells.
