Hello @fonjougiresse wow a great post you've got there. Sometimes the traffic in towns can be too much, making people to reach their destinations late or that makes one to prefer to go to his or her location on foot but we rather just have to exercise patience. You know i remember when i was in secondary around form 3, we had a teacher who always took us to the lab and showed us the things used in the lab.we were always too excited to go to the lab .i remember the burnson burner,testube thermometer and another one that we used to make fun with its name(Erlenmeyer flask😂) .After all what you wrote above,i can join you to say it was really a good for you🌟
