It's my friend's wedding today, and I am invited to the evening reception. I was meant to be going with a couple of friends, but I have glandular fever 
I am worried however that if I don't go my friend will be angry with me, we have been friends for years and I am also friends with her DH. But at the same time, it's just the evening bit isn't it? She wouldn't probably get time to speak to me anyway, but I know it's the principle! But I feel so ill, and really don't know if I could even manage getting ready. I'm just so worried that it won't seem like a valid reason!
