Tender and Raw

Made of glass, fragile to hold,

Emotions swelling up, in an exterior that's cold.

Touch with caution, or you'll setup some flare, 

I'm a gift wrapped in a box, marked handle with care. 

Overtly hard, but inside tender,

You'll breach my insides, the chances are slender.

Breach with caution, lest salty water flows,

I'm a coconut that's obtuse, like a sheep in wolf's clothes.

The shell is hard, but the inner core soft,

Withdrawn and cautious, you'll find me oft.

Approach with caution, or you'll make me retreat,

I'm a turtle wanting to be petted, eagerly waiting for a treat. 

I know I've put a distance, between me and you,

I'm afraid if I let you closer, you may end up hurting too.
