One of DHs bright ideas for DD (She's almost 12!). Here's my main reasons:
1.) I have an average size house (3 bed semi)
2.) On an average day there is enough crap hanging about the place courtesy of 2 children and a DH.
3.) Crap had been moved into the garage. For 2 days I was enjoying my 'extra' space, it almost felt like my living room was the Royal Albert hall I had so much room, now that space is taken up by 'Rex'
4.) Rex is plastic, most mums know the toxic smell of plastic toys, well imagine 6 feet of it. It smells like a 1000 Barbie dolls.
I spent time making the house more spacious and removing crap and putting it into the garage only to have this big t-rex pop up and take up space. I'm seriously thinking about taking a pair of scissors to it and relieving some of my stress, I'm sure the hissing will be very therapeutic 
This bloody dinosaur is going to soon learn that an angry mommy with a kitchen full of sharp things doesn't mix well with a big inflatable taking up her house! I'm going to go on a long cruise if that inflatable isn't popped shifted soon.
