For ‘for’, in dictionaries there are two examples:
- The box is too heavy for me to carry.
- For her, books were as necessary to life as bread…
But I saw this in a video (4:30 here — mostly in Chinese) that if your friend ask you how his new tee looks like, you should say ‘to me, this tee looks nice’ instead of ‘for me, …’, because if you say the latter, the ‘for’ here would be understood as the ‘for’ in ‘if the tee is for me’. But why can’t this ‘for’ stay the same as in the examples above, especially as the second one, in the sense of expressing opinions from one’s own perspective?
