I'm slightly changing my office hours from 2 PM to 4 PM on Thursdays to 2 PM to 3:25 PM on Thursdays. The reason? I forgot about the department colloquium which is held on Thursdays from 3:30 PM to 4:30 PM. I may not attend every colloquium. On those days that I don't attend, I'll hold office hours until 4 PM. Otherwise, I'll wrap up office hours at 3:25 PM so I can dash over to ECCR 265 to attend the talk.
