Instead of moving the sign on the incubator that says "Lentivirus Only" to a different incubator, with someone elses fucken ES CELLS in it, and putting a "Retrovirus Only" sign on the original Lentivirus incubator, could you please fucken come talk to the person in charge of the tissue culture room and see how you can be accommodated to do retrovirus work? Yeah, that's me. I was around all day. No excuse. Thank you.
