its interesting, while reading this i came to the conclusion that he absolutely should not give her a ride home at all.
think about it, it is not a ride home when he is sitting there thinking about shidduch, i can imagine if the girl just wanted a ride home and then the guy is sitting there trying to turn it into shidduch which seems to happen 100% of the time “out there”.
it automatically turns the entire situation into some type of off balanced weazel plank
seriously, tell her she can sit in the trunk.
