Re: Saying Thank You to Dr. Lavelle
Dr. Lavell, I'd really like to thank you for everything you have done for us in chemistry! We see how much you care about us and want to see us succeed everyday! Personally my favorite parts of the course are when you'd show the fun videos or play music before the weekend your jokes are actually fun...
