The last time Mason was gone was in September. That was about 8 months ago. I am STILL pulling these off of his clothes. Socks, undies, t-shirts - you name it. They hide in the most inconspicuous place so that when you think that you have them all then BAMM! there is one more.
They are quite annoying. First off, they are tiny and very hard to pull off of the clothes. But if you leave them on you can feel them scratching at you. If you get them wet and then try to pull them off the ink on rubs off onto your clothes. And really I just can't leave them on. Mason could care less, which is the reason that they are still on there. He just keeps them on... so each piece of clothing has a whole smattering of them.
