my sister and i worked together for a while and it was actually a really fun experience. now i miss her! this is a toughy. but i guess prayer and some practical, reasonable thinking need to come into play. by cursory consideration of the matter it APPEARS that you should take the job. no doubt there are a lot of things to take into consideration, but i'm sure you'll arrive at a decision the two of you and Jehovah will be pleased with.
