OK... Please don't scream at me but I need to get your opinion..

Today was the first day I have spoke to Presley's sister owner for any length of time.. Usually it is Yes no yes no and goodbye kinda talks. But today we spoke and she asked me what I was up to. I told her I was hanging around the pool with Presley and playing with her and so on... She told me that I should bring the kiddy pool up to her place tomorrow and we can have a little party for there 6months tomorrow cause November is kinda cold for the pool... I said I would need to think about it..
I am unsure of what to do.. Presley was so scared of these people last time they were over. I miss my friend so much. It is selfish of me to want to be friends with her but i do miss her. I know Presley has a blast playing with her sister and their other lab. I don't know if i should take her over there......

so confused...
