The weather in my city today is as bright as my heart.

This sounds great and I must say that I am impressed. For your students to ask to take a photo with you means they really value you and see you as one of the best teachers ever. You know, taking photos is for remembrances.

Indeed, you really had a great day filled with many blessings. From meeting new friends, to buying for someone you just met, and many more, is something that I admire so much. I wish you many more beautiful days ahead for you to keep on enjoying and making people happy.

Best of luck to you and thanks for the invitation.
