Mukunda

Last week

• Worst thing
  • I cut my index finger pretty bad doing stupid things with a pocket knife
• typing one handed currently :(
• Best thing
  • I still feel my fingertip so I don't think anything's permanently damaged ;)

I'm probably going to request the rest of the week off, since my typing is impaired and I don't have any train duties or urgent projects to work on this week.
