I remember when someone stole everything I owned (which wasn’t very much as a 21 year old grad in London). Memories as vivid as the ones you describe will long term replace the yearning for the material. I pitied and hated the person who robbed me. Turned out he was a raging drug addict and they caught him trying to sell an old watch of mine. For his last hit. Stay strong and draw on the love and beautifully enveloping imaginations of your wonderful children. Good luck in your new place.
