The system I use is tell her the odd thing I buy and the rest I click and collect so she doesn’t know its when she goes on holiday with her mates the postman and me are on first name terms for a fortnight it’s simple it’s only on odd occasions if she pops into the shed and spots something new like two torque wrenches I smuggled in mind you she never noticed the Akra I fitted
Wow! That seems like ages you've been at the in laws. You'll be rapt to get back in your 'new' home! Another Mini Moto maybe? You know, buy now to beat inflation and Brexit price rises. Or a baby aprilia RS 125, just to familiarise him with cleaning and affixing decals?
Nearly 3 months  all life's emotions been played out via emojis!!!!! He'll be getting the mini moto hand me down in due course...... However he will be about 3 so it will be like a full size bike!!!!
She does my accounts, and she is very creative at accounting and gets my full akrapovic system as a Nissan Navara parts purchase
