What to say when she texts "I'm outside"

Her text is a report, not an invitation to chat. She has arrived, she may be cold or a bit awkward, and she is checking whether you are coming. The message is short on purpose. People waiting for a first date keep it flat so they do not seem needy, which means a missing question mark is not a sign she is cold toward you. Check what time you two actually set. If she is early, she may have planned on a few minutes of waiting, but she will not wait indefinitely in the cold. If she is already seated somewhere with a drink, the wait is more about whether you will show up at all. Read the situation first, because it tells you how much time you have and how much warmth she needs in your answer.

The first reply has to cover the delay without turning it into a scene. Acknowledge that she is waiting by naming her position, since she is the one standing out there. Then give a number of minutes you can really keep. Padding the estimate feels safe, but it makes her wait longer than the message promised. A reason is optional and should be short. Anything beyond one clause starts to sound like an excuse, and she will spend the next few minutes reading your excuse instead of settling into the evening. The last job is making the next step easy. Tell her where you would like her to wait, whether that is inside, at the table, or somewhere with cover. That stops her from standing alone with no instructions, which is the worst part of being early.

Send the reply within a minute of seeing her text, not after you have finished getting dressed. A quick message tells her you know she is there. If she does not answer right away, that is normal, since she may be walking or waiting on a light. Do not send a second text asking whether she got your message. Put the phone in your pocket and get out the door. Send one more short update only if your estimate changes by five minutes or more. If you are still not out when the time you gave has passed, call instead of texting, because a call shows you are moving and a text chain makes her read every minute. If she says she is leaving, let her go. A rough arrival is recoverable, but an argument about the wait is much harder to fix.
