Do not.

[alex_antonin]

The sentences that will fill me with the most foreboding and anxiety spikes are "We need to talk" and "I have a bone to pick with you." If you're my friend, don't ever use one of these sentences around me, not even in jest, because every time I hear them I think "This is it, this is the moment I lose another friend and/or get in even worse trouble for some reason."
