get in sb's hair: annoy sb by preventing them from doing sth (因妨碍而)惹恼某人
I can do the housework much more quickly when the children aren't getting in my hair all the time. 要不是孩子老烦着我的话,我可以很快做完家务活.

Can't make head (n)or tail of sth: not be able to understand sth at all 一点儿都不理解,茫无头绪
I can't make head or tail of this pitcure---is it upside down? 我看不明白这张画---是拿倒了吧?

^.^背景音乐不错吧...
