This post is a little war story about a time I helped out a friend of mine. My favourite movie for 2017 was John Wick Chapter 2. Not quite as good as the first movie but still awesome. In one of the  scenes Laurence Fishburn shouts “Somebody, please! get this man a gun” Just prior to Christmas a

In preparation for watching Star Wars The Last Jedi I’ve begun watching episodes 4-7 (I have little interest in watching 1-3).
