Yes I don’t usually like to ask unless I have a concrete practical reason (work or volunteering) I’ve also become more reluctant over time to ask for this. I will offer my number to people easier though as it is less intrusive to leave it with them.
I’ve also not felt comfortable sending friend requests on Facebook either when I was previously more comfortable. I have been withdrawing more since maybe the pandemic. Don’t know if this resonates with you.
Do you feel like you’d want to ask for numbers more easily or are you okay with it as it is?
