once bitten, twice shy

Just in order to protect me and who I love, I will always smell a rat.

Even having a proper and healthy conversation, explaining about cordiality and good forms, trying to make a miracle indeed...  A carrion kite will never be a good hawk!

People don't change! Good-for-nothing... Sorry.

relax

I am very sure of myself. 

 *in my way:

Once burnt, twice shy!

(Don't piss me off!)
