Sounds like a plan

For me, yeah, something can rub me the wrong way and maybe the totality of an old friendship or aquaintance may be a positive one, but unless the person becomes openly hostile and combative towards me, I tend to shy away from that block/unfriend button. I'll certainly distance myself, not that I don't sometimes discover distance by being caught up in my day to day life, but I do at times consciously choose to protect myself through walking away or stepping back.
