First off, it’s OK. We all make mistakes and misrepresent our feelings sometimes, which can affect others in ways we don’t intend. The particular social accident you describe is also quite common. I promise she will quickly recover from the inadvertent rejection.
My answer is: practice. 8-9 years is a long time to be out of practice at anything of this sort.
There are a variety of ways to actively pursue that practice, some more creative than others, but the most natural way is simply to invite interaction with others in general such as, apparently, drawing on a bench at the park :)
And the hand-count auditing of machine results for mayoral primaries is usually overseen by just a handful of people. It’s way more achievable. Tampering with those machines is easy by comparison.
IMO if the conspiracy hinges on “hacking” voting technology, it almost certainly overestimates not only their internal complexity but their role in determining election results.
