Before communication for help, you need to familiarize yourself with joining society. The walk and cafe thing help with that. Be comfortable with existing within society for a while. That by itself invites some, if not more, people to engage in a conversation with you. It's a learning process. You get to understand being social when you expose yourself to it. And ደስ የሚለው ነገር is that Ethiopian people (mostly) are friendly, so you don't have to go out of your way to communicate with them. If you're in school, be active in group works; if you're an adult, be active in the work environment. I'm not telling you to magically be an extrovert. I mean active as do not isolate yourself and be inviting. These exercises are enough to help you become naturally social. Hope this helped. Cheers✌️🏾
