I debated with myself for quite a while whether I should send this to you or not, but figured it would probably be better to talk to you about it in person. I still need to get this out now, or it will fester in my mind all day, but if I tell you over message that will ruin your day.

I don't know what's wrong. When I asked you last night it was "nothing". When I asked you this morning I got "I'm fine". But I know you. I know when there's something bothering you. But I can't read your mind. So how am I meant to make things better if I don't know what's wrong? I don't want you to resent me ever, for any reason, never mind for something I've done without having the slightest inkling of what it may be. If there is a problem, tell me, so I can make the effort to fix it. Or if it's a question, just ask. I don't know what I've done. Or if it's even me that has done something. You were absolutely fine when you got home yesterday, and in a few short hours, something happened. I just don't know what...
