I am baffled about this and I need your opinion/suggestion.

If you are a full-time internet entrepreneur, it is possible you spend many hours at home; you would probably be glued to your computer, while other men go to their conventional 8 to 4 jobs.

There is risk of neighbours seeing you as a jobless man or someone with questionable way of life, since they may not understand why you should be at home while everyone else is at work.

Consequently, neighbours may report your "suspicious" activites to the police/ civil defence corp.

If police/civil defence (guguru defence ) now arrest/question you, what will you tell them is your job description? Or how will you defend yourself? Please, I need your suggestion.

In the first place don't laugh with neighbors. Don't answer any busy body who might want to question you as if he/she is a friend. Mind your own business and let your body language say: everybody should respect himself/herself.
That's the only way you can avoid unnecessary embarrassment.

simply tell them you are a web developer and internet expert. this is why its advisable to rent a shop and use it as your office.this way you tend to even get more people to come by your office for business, meetings, verification, one on one teaching etc. now a days people tends to know if you have an office before doing business with you. also, for security reasons, you wouldn't want to use your house as a teaching spot, meeting spot etc

Don't concern yourself with the opinions of busy bodies

Great minds discuss ideas, average minds discuss events and small minds discuss other people. If your neighbours are talking about you behind your back dont let that disturb you.

Focus on building your online business diligently, do all the things that most people wont now so you can live a life that most people cant.
