summarizing stuff

I love summarizing stuff, If there was a job for summarizing stuff I’d probably do it for free. I find most often that I have trouble reading school/college books, but whenever I want to summarize such a book everything seems to click. I sorta start thinking about other people and how someone else would be confused by the book’s content, and it becomes a battle between me and the original author.

nearby share a brief synopsis

First day into Sanna University, the teacher wanted to share some PDF for us to study. This began as one of the most awkward encounters. Basically the teacher was looking at her nearby devices in the bluetooth menu, and was calling names such as “Who is J7?” “Is J7 Here?”, etc etc. So it was basically half an hour of calling device names and getting no replies… In that moment I thought of making the app, it would rid me and other students of the hassle to constantly wait for resources that we need to have in-order to study.
