Today I went to pick up my son and nephew, and I usually have a ton of stuff in my hands leaving my nephews room. Today, while I was waiting for him to give me my nephews stuff, he said "oh I'll bring this to the front for you" he walked with me to the cubby, put the stuff down, and said have a good night and see you later. Thats the kinda thing where Normally it seems like nothing but with the other things he seems to do and say, I'm not sure. Some days he seems obvious with his flirting ( if he is flirting ) and other days it seems more subtle - like I have to think in my head whether or not he was flirting.
