Should you text them if you see them in public somewhere?

A quick hello with a smile and a bit of conversation usually means they noticed you too. A friend standing next to them, a shopping bag in each hand, a quick wave and a glance at their phone usually means they were busy and would rather not be caught mid-errand. Check the basics: did they stop, did they hold eye contact, did they introduce you to someone, did they say anything about meeting up? If it was warm, you have a reason to reach out. If it was polite but rushed, the text has a different job: keeping the earlier connection alive without making them carry the weight of a reply.

Also check how much you've talked before. Two messages on an app and a match from last month is different from a second date that went well. The more real the contact, the more natural a text about running into them feels. With someone you've barely spoken to, a short note can still work, but keep it light and avoid anything that reads as surveillance.

The text should point to what you actually saw or shared. Mention the place, what they were doing, or the small exchange you had. That tells them you were there, not that you ran a search or sat in your car for an hour. Skip describing their appearance, guessing where they were headed, or commenting on who they were with. Those details can make an ordinary coincidence feel like tracking, even when it wasn't.

Give them an easy way to respond without having to decide what the encounter meant. A light question about their week, or a note that you'd like to pick up the conversation somewhere more relaxed, does that job well. You're not asking them to confirm interest in the same message. Just let them reply however they like.

Send the text the same day or the next morning, while the encounter still feels like a shared moment and not something you're digging up from memory. Late at night is the wrong time. It looks like you spent the evening replaying the sighting, and it puts them on the spot.

If they reply warmly, match their energy and suggest something concrete if you want to meet. If they reply briefly or not at all, leave it. A reply within a day or two is a normal window. If three or four days pass with nothing, one more light message can be fine only if you have a real reason to write, like sharing a link or a plan. Otherwise the conversation has ended. The kindest move is to let it stay ended, without a follow-up that asks why.
