PHASE OUT A TOXIC FRIEND

First phase: The E-freeze 
Don't email back. Got a second message? Wait three days to one week to respond.

Second phase: The "three weeks from Tuesday" evasion 
if the offender asks about your dinner plans, say your calendar is packed, but you can meet... then cancel.

Third phase: The "So busy" defense 
By now, the offender may be on to you. Say you'll call once your schedule frees up.

Fourth phase: Full disclosure 
Should the offender be unable to let go, you'll have to come clean. Really, who would want to still be your friend at that point?
