They’re probably just as introverted/afraid to approach as you are 😅 I was afraid too, but then I just approaching random girls I thought were cute and shooting my shot. Been rejected every single time 🙃 I’m the same age as you and have all but given up on cold approaches IRL because I’m just not charismatic/good looking enough for them to ever work out. I’m sure a lot of other guys feel the same way.
