I think going over if she is ok with it would be great! Also you might ask your sister if there are things that she has issues doing - although 59 is really pretty young. Maybe you could help out around the house, cook a meal or something she doesn't like or can never find the time (meaning she really hates doing it) to do. You never know you might be able to work something out to the benefit of both of you! I have a friend who is way more tech savie than I am and I sometimes trade her quilting for her help. It sometimes is somthing I could do but just won't because I hate it, like she is scanning my patterns in so that I can have them digital and make room for something else. I have another friend who has been helping me wrap and organize my fabric. Now if I could only find someone who was willing to trade housecleaning for quilting!!!!
