Phone number or other contact info. Supposing you’re on good terms, they’re not someone you’re interested in romantically or the like (so none of the anxiety from that at least), what’s kept you from asking?
Supposing that something has on occasion, anyway.
Absolutely this!
As a dad, I was always extremely cautious when I was out with my kids talking to moms out with their kids. I also talk about the now, because I’m not trying to confuse anybody.
One of the more uncomfortable moments: my kid was playing and interacting with a child & parent. I said hello. She immediately took her kid and left the play area.
Another time: I must have been talking to a single mom because she kept asking me to be her 3 yo’s male role model multiple times.
I gave up trying to make friends with other parents at playground areas since then.
