Height is such a petty thing to lie about. If he can lie about something as tiny as this, you should be wary of what else he could be lying about. Definitely a red flag.
Once went on a date with a guy who is a 'financial advisor'. I asked him if he has any investments of his own, but he said he didn't have any as he was 'investing on himself'. He also doesn't know jack shit about bonds and index funds. He did sell me life insurance though. 😂
