Recently my brother passed away suddenly leaving behind my sister in law and 2 adult children in their 20's, They live a 3 hour drive away. We weren't particularly close, we remembered birthdays, Christmas and got together maybe once a year, my parents are also deceased. I want to be there for my sister in law and keep in touch as much as I can, I'm the only link in to my brothers family which I think is important for my niece and nephew, telephone conversations I find awkward as we don't have much in common, I'm too far away to drop in with a food parcel. I can keep in touch with my niece and nephew as they both use social media but my SIL doesn't. I have a thinking of you card but I'm stuck as what to write in it, hoping for some wise mumsnet advice please.
