Paper towel on a hard surface, drop egg to crack shell, roll it under your hand until it’s all crackled, then pick out a piece that lifts the membrane and peel it off like skin.
Give it a rinse after to remove any particulate. Humans really shouldn’t be eating the shells in chunks as it can get caught in appendix if you have one.





You could always temp some customer service jobs where you’re in contact with more public to see more faces.
Sit and people watch at a coffee shop by a bus terminal, park, community center, mall.
Lots of opportunities to observe faces.
Just don’t be creepy about it tho.
