You raise some really important points.It is hard to find the middle line sometimes. It is wrong to take advantage of others but it is also important to recognise our worth and stand up for what we deserve. So hard. It took me far too long to learn something that should have been obvious. "You are much more likely to get what you want if you ask for it." I think you should ask your friend for a 50% discount at the air bnb. Or a free stay. If i had an air bnb place in the swiss alps I'd let my friends stay free. A🙏💚
