Do piecewise functions have parent functions?

Who is responsible for transportation to school-sponsored functions when a child is at the other parent's house every other weekend?

• Answer:

  The parent responsible is the one with whom the child is staying with at the time the function occurs, unless, physically or schedule-wise, it's impossible for that parent to take the child to the function. (Parent has to work at that time, cannot drive or does not have their own vehicle). In that case, the other parent should step up to the plate, or make prior arrangements for another relative or friend to take the child. What matters here is what's best for the child, not either parent's resentment. If this issue can't be resolved privately between the parents, a family law attorney or professional mediator should be contacted.
