So my bf and his brother had a long term nanny and she has two daughters... she took care of my bf and his brothers for 15 years, and her daughters are all around the same age on their 20s. They also lived with them for a while bcus she had lost her home before. So I went out with one of the girls and she had a few drinks and she showed me texts that she had sent to my brother in law. It was so cringe!! The texts were like "you look handsome on ur picture😍" and he was like "oh thanks lil sister" .. because that's how we view them - as family or sisters! Then she went on telling me how she thinks he fancies her a little, tbh I just wanted to "throw up" bcus it sounded so wrong and creepy.. I couldn't preceive this properly tbh
