Ok, so I borrowed a friends video camera to do a film, and its memory was full after about 10 mins of shooting. So I told my friend who was filming to delete the scenes that were bad, and we still ran out of memory too fast. I then deleted a video project that my friend and I made last year, because I figured it wasn't that important compared to her personal family videos. Well, somehow it seems that all the footage on the camera was deleted and I didn't even know it until right now, a few days after I gave it back to her. Now she is pissed off at me since those family footage is now gone. I have to admit she told me not to delete anything, but the memory card was full after 10 mins, so I had to delete something, so my intention was to delete something not very important. Basically now she isn't on speaking terms with me and it is awkward being in the same class, since we share a lot of mutual friends etc. I can't go back in the past and not do it, and I can't retrieve the deleted stuff I think, so everything is sort of out of my hands. How do I approach this? Do I explain that it happened and I can't change it and I am sorry for accidentally doing it, or do I leave her alone and let her steam off and wait for her to finally get over it.
