I'll start off by saying that I haven't said anything/told this person how I feel and I won't either, before anyone jumps on me. I just wanted to get other peoples opinions.
I'm making my rounds this week, dropping off presents to family and friends. The days running up to Christmas will be busy, the same for everyone I'm sure. I'm also working until Christmas Eve and wanted to get things done early rather than running around like a headless chicken the day before 
I bought some presents for my friend's children and asked her last week if I could pop by on Thursday (yesterday) which she said yes to as she had no plans. I wanted to give plenty of notice as I know everyone is busy this time of year. I messaged her yesterday morning to check all was ok and she replied that she was having a lazy day with the kids and could I come on the weekend instead. I already have plans this weekend and wasn't sure if I'd have enough time (she lives an hour away). I mentioned this and just asked if I could leave them by the front door instead which she agreed to. She messaged me a couple of hours later saying thanks.
AIBU to think this is a bit, well, shit? I'm pretty sure they were sat in the living room when I dropped them off. I'm not sure I could just sit there and not even say hello if a friend was outside my house. I understand it was my choice to get them something, but if someone had made the effort for my kids, I'd certainly acknowledge/speak to them, even if it was just for 5 minutes. Being ill or having something crop up is of course different situation, but they were literally just sat on the couch watching a film by the looks of it...
