I think in this case April fool went a good way for the lady. The guy was "April fooled", haha. Nevertheless, like you mentioned, we should be cautious of people's feelings and there should be a limit to this thing, if at all it's even needful at the time.
Honestly to me I don't see the need of the April fool day sef but it is what it is
Thank you for reading
Lol.
It is what it is...indeed.
