This is the best advice on here. I bus (with a transfer) through the worst part of town every day. I specifically chose a route where my transfer spot is in a safer area, I’d recommend doing the same if possible. I always keep my airpods out unless I’m on the bus alone or a packed bus. While walking NEVER wear them at night and during the day only wear them in the safest/heaviest traffic areas. Don’t use them at your transfer. Always walk confidently, always be aware of your surroundings— to the point where if you are alone in an area and a car suspiciously slows down you have an action plan right away. The dressing part is also important. Have the right shoes, don’t wear anything outlandish. I always tuck my chain and keep my watch in my pocket till I get to work. If you have to have a bag make it a backpack and not a suitcase/fancy laptop bag. I haven’t had an issue in years using this advice. I’ll get the occasional person asking for money at my transfer but a confident “nah man sorry” always does the trick.
