Just a little bit to much !?? Rubbish!!! Lets laugh again !!!

I´m really proud of my parents !!!
No , really!!! I don´t mean it in a sarcastic way.....I´m very serious.
First there was the day when my mum offered Sam to call her Andrea and not anymore Mrs.Burns. Sam looked like he was in the mood to say anything that my mum definitely don´t want to hear .
But then he smiled and said politely "Thank you Andrea ".
So everything was fine.
After my mum offered Sam to call her with her first name my Dad hadn´t got the opportunity as doing the same.
Both of them really try to make an effort with Sam but sometimes its a little bit to much .
E.g.Yesterday : Sam told us that he wants to study after school and that his grades are going to be better . Which was absolutely meant serious but my parents laughed and laughed and laughed.
Thats what I meant as I´ve said sometimes it´s a little bit to much.
At the same day as they had decided to laugh about the unfunniest thing in world they had also decided to ask where Sam and I were going to live with the baby .
Of course had we talked about this problem and we, that mean Sam and me, decided to live here in my house.
OK now its your turn to guess how the reaction from my parents was ....
RIGHT!!!!
They try to convince me that we were doing everything false but what am I saying they were not only trying to convince ME they also tried to convince Sam...
In their own way ...
Especially my mum ,she said that its terrible to share a bedroom with somebody. Which means with other words its terrible to share a bedroom with Dad.
I mean , what is she doing?
Does she wants to kick Sam, me and Dad out of her life ???
