@Teriyakieverything congratulations to you/your DC too.
In one of my DD's first NatSci lab sessions, the academic in charge gave them all a strong message. She explained that whilst the lab was meant to be from 2-5pm, due to the nature of the content, some weeks may finish earlier, but many more might be later. She then held up a bike helmet and bike lights and said that these were life savers. Labs would finish after it was dark and anyone stupid or arrogant enough to think they could cycle without them was not welcome in her lab. DD was stunned and impressed.
In DD's 2nd year, a lad from the year above at her school and in the same college was involved in a very nasty bike accident which involved a bus. I don't want to give more details other than to say that his helmet undoubtedly saved his life and he has made a full recovery, but it was a reminder to all of the value of helmets.
Finally, whilst I don't think DD plans to supervise any freshers this year, she will be doing demonstrations in the labs so may encounter some of your PhysNatSci DC!
