Thank you, Joel

This afternoon when I went upstairs to Classes 313 and 314 to give them my handouts, I found on the landing of the stairs on the fourth floor some leftover and litter scattered. It looked disgusting and dangerous.   "What if someone steps on it and slips? Why didn't anyone who saw it before me care about it and clean it up?" I thought to myself.  Then I asked in Class 314 if there was any volunteer who would help do the clean-up.  Joel (簡喬) raised his hand before his classmates did.  He did the job thoroughly.  Then when he was ridding the dustpan of the leftover and litter, I noticed that he remembered to do recycling.  Thank you, Joel.  You might have prevented someone from slipping and getting hurt.
