Ask for a date

Tell her when. She will confirm.

There is no calendar to fight with. Ask for any date, however far ahead, and you will hear back on WhatsApp or by email — usually the same day.

Where should it happen?
Any day at all. If it is not possible she will say so and suggest another.

Both, please. Your confirmation comes by WhatsApp first, and the email is the backup for when a number is mistyped or a message does not arrive.

The occasion, your area if she is coming to you, allergies, a look you have seen. Optional.
