Taxis to and from events (Lima)

I moved to Lima 2 months ago and I have seen many events I would be interested in attending, but it seems everything is Miraflores or Barranco. Both are lovely areas that I enjoy but I live in La Molina. I am sure I can find a taxi to take me to any event but I worry about getting home. Is there anyone else in La Molina that would be willing to share a taxi? Any other suggestions about how to handle getting to and from events?
