Another Computer?

Alycia and Sherilyn have been demanding a lot of my attention lately. When I am seated in front of the computer doing my work, they will insist to be read to from the computer. There is no way I can stop them from hoarding the computer and I always end up letting them have fun reading on my computer for at least half an hour to an hour. If this continues, I will probably need to buy another computer for my home office and get a KVM switch.
