I used to have a hard time with the "bear" expressions (I can't bear it, or bear with me, etc.) until someone (jokingly) asked me if I wanted to get naked (bare). Ever since then I have been able to remember that unless I want to bare my soul (make my soul naked) just about all the other expressions are "bear."
I bear you no ill-will.
I can't bear to be away from you.
Could you bear with me a moment longer? I'm almost finished.
Although you did get the answer already, I hoped my little story (and hopefully your desire to NOT be naked) will help you remember.
