My friend is a follower

So she has a statue and I end up taking care of of Santi more than her. I talk to her, change water, give her gifts and everything. I feel I wouldn't because I'm not the follower I follow another I also do the same for him.

I like Santi know these things I give her are to bless the house and my friend and they are in away from her not me. I'm simply doing it for her because I know she would like it done.

Santi wears my Nana's rosery. I have it since I wasn't using it. I feel weird doing for her in my friends place I feel like she's mine? Or for me more than my friend. Maybe I'm looking more for advice or something but should she be doing more? She is going through a stressful time in life right now though I'm pay off the problem no doubt.
