Parents...never fail to amuse

Continuing on from the title...many readers may know that one of my best friends is a guy.
for a long time now, my parents were not aware of this and lived in blissful harmony with their supposedly "good kid".
The other day something came up and they forced me to tell the truth as they had been hearing me talking to someone at night time. this was obviously my mate calling me. As human instinct called, I lied...but my parents were smarter than that. 'It's a boy isn't it?' they said, ever so confident. of course I couldn't deny it anymore. And they knew exactly which boy as well...
Parents continue to freak me out...
how they know I have know idea...
I think I want to be a parent just to learn their secrets...
