Task: Question Answering
Input (English): Oh well . Everyone has asked me how the year has gone and to be honest I find it difficult to sum up . It's been long , and it's been hard work , and on occasion it has been scary and on occasion it has been thankless . However , in general , it's gone great - I've learned loads , I've made new friends and I've settled into my career . It wasn't all champagne and celebrations on the last day , because to be honest , I stopped feeling like the anxious new boy a while ago . 
Question: Why is it difficult for the writer to sum up the year ?
Output (English): Because a lot has happened in it .
