In the presencec of known hostile people

What do you when you are forced to get along with someone who you dont get along with or possibly know you should keep your distance from?

I should have known times would come around like the holidays when an abusive family member would stop by while I care for an elderly parent. My younger sister moved out but still visits. To avoid conflict I keep all interactions with this sister strictly casual and avoid topics that trigger her hostility you can say that is controlling or enabling but it is the only thing that works and sad that I have no choice in the matter due to other crazy ramifications which would prove to be a waste of time and energy… Meanwhile she can bring up what ever irritates her about work experiences and how terrible other people are at the office and do it fpr sport not like it is really bothering her so I just let it go on and wait.. and think of something like... Well would you like some egg nog? As I hang around waiting for her to move her care while she is being casual. My younger sister has been largely unhelpful with caregiving but visited on Christmas Day.

Christmas was stressful for me and nearly missed due to nonstop house repairs, caregiving, and exhaustion I could only hope to write out a few cards to people who wrote me and take it upon myself to bring them to their houses and deliver them but I first had to check the antifreeze and as I was doing that and found that their may be more trouble with the vehicle than I thought I then had to proceed to try and fix a problem to keep the vehicle going and that’s when my sister who parked in the street came to visit and walked up the driveway

I thought it was a good idea to run the errands delivering cards while observing and letting this special additive circulate in the cooling system of the special-needs van used for caregiving and in the mean time I was hoping for my sister to be gone before I got back but after returning home my younger sister was still present and had now parked her car sideways, blocking the garage.

The blocked garage prevented me from parking the van  in the garage so I could pull down the door and pray hope and forget about it and hope the bars leaks solution I put in would work a miracle and keep that thing going.

So I had to go inside and asked politely for my sister to move her car despite feeling frustrated to say the least because this parking behavior has happened before and caused serious stress, physical strain, and conflict in the past besides my sister had plenty of space to park properly and ignored the guest parking area. This situation reopened old wounds from past abuse and inconsiderate behavior. And once again I feel unheard, disrespected, and forced to “keep the peace” despite ongoing stress The added stress felt unnecessary and deeply upsetting during an already difficult holiday.
