When my dad died my wife, myself, and our two boys, moved in with my mom because she has no idea how to take care of normal life stuff. My brother lives in the same property as her and couldn't be bothered to check in on her because he was, understandably, distraught. For two years of living there my mom leaned on me but only ever asked me once how I was doing, my wife only ever complained about living there and never asked how I was doing, yet insisted we should stay if I suggested leaving. I have three super close friends, and I don't think I would have made it without them.

Check in on your friends, even when they're not going through something traumatic, because you may be the only one who does.
