Damn I forgot I was doing something like this.
So I forget a lot and fast.
Today I got up from my desk to drink water, did all sorts of things except drinking then came back to my desk. It wasn't after long I realized I forgot about it.
Pretty sure this happens to everyone when they enter a room with the intention of doing it and immediately forgets.
On another note, blaming these things on ADHD is soo much easier.
