['I had to give a big presentation at work today. I prepared really hard for it. Unfortunatley when it became time for me to present I got really nervous and just froze up.', 'Ohh, I feel sorry for you. It happens.', "Sadly yes... I don't know how I'll get over it though."]

I had to give a presentation at work that I really prepared for. But when I began it I forgot everything that i had planned on saying.
