Are you watching where your going or daydreaming? A nod or finger lift is fine,anything is fine. At work most walk with there heads down and i'm not much on saying anything but ALWAYS get eye contact and smile. Thats hard when they dont look at me. Well at my last meeting it seems people are having a problem with me not saying anything or talking to them. The fact that i get my work done and service them quickly isnt good enough.I was told i need to be more cheerful. Lets see,i might be having 2 bags of trash in each hand going out to the trash bins and on my way to clean up some vomit and check on a bathroom as i'm on my lunch half hour which is my time and only one chance to have lunch and they call me on the walkie-talkie to go to a room and replace a bulb and go to the far side of the school to unlock a gate.When i get to my walkie-talkie and out of breath say,ok,i'll get a call from the VP saying,that wasnt very cheerfull on the walkie-talkie. I'm always being told how much the teachers hate me because i dont stand around and talk to them. Lets see,i get a call,i have ants in mt room. I spray inside and out,clean up the dead ants and tell the teacher,thats about all i can do. She goes to the principal and says,dan said he cant do anything for the ants. She says why did i say that,i tell here what i did and she tells me,do more and dont say you cant do something. People.
