Grow some balls Jerry
Tell her it’s you or the bike
(no, maybe not)
You need it to ride some Vinduro’s on.
Tell her it will help you stress relieve after a traumatic day at work and thus making you much more enjoyable to be around.
You need space to find your innerself
Encourage her to have an affair, then she won’t mind you going away for the weekend
Or just hide it at a mates place
Tell her its for your son and you need to test it for him to ensure it's safe for him
It's an investment
or
It didn't cost you anything, the bloke was throwing it out
Surely you can bullshit a bit, you do know how to bullshit to your wife don't you?
