I lived for a year with my parents in law and never realized that they knew about us until the day I went to see my doctor along with my MIL, the doctor asked me few questioned which I answered and when she asked "when did you have sex last time" my MIL quickly replied "Last night".
Believe me that was the most embarrassing moment in my life.
helmet cat / Hareem! It's too funny and embarrassing.... nice try but I wouldn't not believe this is true - cause believe me even dactaar's know not to ask this type of question in front respectable "other" relationships that tag along.
but it was funny indeed:)
