Public appearance and public transport

Boring topic eh?
Well, I go out today. By public transport.
I think its been awhile since I appear in public. Hahaha that sentence makes me seems like somekind of celebrity.
But that previous statement is true nevertheless.
Being in public makes me kinda nervous. There are strangers staring at you and once in awhile they come up to u to ask questions.
Example, today, 4 strangers approach me to ask direction.
Why me though?
Do i look harmless when im traveling? Hmmmm
