Dear Mr. Singer,
I know it's been a difficult week for us. I've been quite demanding on your time, and as a result, you've lashed out with tension issues and a broken needle.
I resisted the urge to throw you down the stairs last night, and instead called Mum and lovely friend HH for guidance. Thankfully, after a little bobbin re-threading, we came to an understanding and started making beautiful projects once again.
Don't worry, I'll give credit where credit's due and be sure to sign both of our names on the Christmas tags.
