Blood and nose

I was clearing my nose of mucus (what? QueenPig needs to clear her nose like you too!) yesterday when I notice there's little 'clots' of blood.

Is this normal?

I suspect it's related to the knock given by dearie Pey Lun last Saturday. Shall see if I notice them again.

On a totally different note, some of you told me that there're weird 'notices', banners and forbidden areas on my blog. Where are they? Do they change place? What's on them?

Someone teach me how to remove them~ >.<
