Blipless Day

I was supposed to be at a friends this evening but had got to go to bed early to try and shake yet another head ache! Maybe I should get my eyes tested, or maybe it's just been a long day at work. I don't teach on a Wednesday so spent most of the day working on the computer. I don't know how people work on screens all day. I nearly always end up with a headache :-( Looking forward to getting back into class tomorrow...
