hello @sailawana dear your post like you had a busy and fulfilling day! Teaching about the respiratory system, enjoying snacks with friends, and having a pleasant meet-up at a cafe make for a well-rounded experience. Your descriptions and the accompanying images provide a vivid account of your day. Keep up the positive interactions with your students and friends. It's wonderful to appreciate the simple joys in life, like sharing a meal and catching up with a good friend. Have a great evening..
