Is it normal that i notice that something is missplaced?
I notice when someone changes something's position. For example, I left my pencil case alone for a moment and when I came back, 2 pens were switched. (My pens look very similar so is kinda hard to notice) Of course, It pissed me off,when I asked about it to my classmate he asked me how I noticed,and why I got so angry.(It has him who switched the pens)When I couldn't answer the question myself I came here.
Sooo..... Is it normal that it pisses me off?
Note: my pencil case has holes were you "stick" the pens/ pencils.
