Do You Have Keepsakes?

I assume the question we should be asking is 'why' she is doing this? Are they short of space, are the items unhygenic or is it done out of malice? Regardless I don't personally feel she has the right to dispose of his belonging with at least letting him know of her intentions. How would she feel if he started getting rid of her things without telling her - I'm guessing she wouldn't be very pleased.

My wife does it all the time, especially t-shirts I've had for years, I use them for when im decorating (that's my excuse anyway lol) when I go to find them, she'll say I throw them away
