Here girls are offended that men do not notice anything. I cut my hair. And if for a guy to cut his hair, it is specifically to change the hairstyle, then the change in hair length by 5-10 cm is not very distinctive. Also small things like another tone of mask, lacquer and so on. But I'm paying attention to such unobvious things as the disappearance of condoms from the servo, a pregnancy test in her bag, calls from left phones at 2 p.m.
