I found that people will not be offended if you suggest a first date before they are ready.
Dating advice how many dates
It’s not as if you hoping to “chat” with someone and end it there.
You want to talk with them and if things go well meet them.
Limiting the time of the first date is a safety precaution: if you end up on a nightmare of a date you’ve already established your “out”.
If on the other hand the date is going excellent, suggest to your date that you extend it.
It is personal preference on how long to wait but there are very few reasons to delay.
