Get a gas pistol. Tho if that lost soul decided to threaten me, he should pray that somebody would be around
The assault(s) on me changed my own attitude towards self-defence and there's no place for fear. I was beaten at high school by a bully and imagine going to the same class with that person after that, every day. You will have to overcome fear & thoughts about avoiding problems.
After being raped I promised myself that nobody will ever hurt me again. Tho I control my rage against such people but I'm kinda "lucky". In 2 years after that some homeless man threatened me with a knife at the biggest avenue at 21:00 (but there was noone around) simply because he didn't like me walking beside him. I chose to walk away because I felt sorry for him + I kept in mind heavy traffic and that somebody could call police on me, I've got no time for all that bs.
Lulz @ shoplifting but having money for a bail. Such people rarely come back to the same place where they had commited a crime. It's your attacker who should be afraid to meet you again. They are afraid & having issues too. If he's dumb and he wants to rob the same place twice or have a revenge, then you better prepare yourself
to whoop his ass
ps. In any case, overthinking that accident will make you stronger with the right approach.
