I'll try and keep it short and sweet. In 2018 in September, a colleague very kindly gave me a folder of resources for my third subject to dip into when I needed. I put these in my cupboard, and rarely (if ever) dipped into these. Fast forward to now, and my colleague has asked for them back. Went to look in the cupboard... and they are no longer there. Searched high and low. Nowhere to be seen. This colleague is a cover supervisor, so did me a massive favour in giving me resources at all.... I feel terrible! Now she is covering this class again, and I have lost all of her resources, she is going to have to start from scratch with her preparation.. She is not a formal teacher and worked hard to collect what she had. How can I go about making this up to her?!
