I have fed a friend's cat for 4 separate holidays this year. She has done one week for me. I have decided that I really don't want to have to feed her cat over Christmas. On Christmas Day my kids will want to focus on present opening and I don't want to go out after Christmas dinner (it's 1.5 miles away along an unlit road). I was wondering whether to tell her this but instead thought it would be better to just mention visiting my brother over Christmas. I am going to see him, but only on Boxing Day. So the friend asks what I'm doing for Christmas and I say 'going to my brother's'. So far not a complete lie, but then the friend offers to feed our cat (having previously said she may be away for Christmas). I was caught unawares and just told the blatant lie that another friend had agreed to do the cat feeding. I'm wondering if I should just have been honest and said I don't want to do cat feeding over Christmas.
