The speaker looks back on losing nearly everything during a hard stretch of life. Photos and keepsakes from people and places disappeared, leaving only memories. Later, a new collection builds up, but it sits untouched on a wall for years, and eventually the speaker drops the action figures in a donation box. They were "just toys after all," a line that sounds casual but also suggests the speaker has learned not to cling to objects.
Music and movies now live on a hard drive, so the speaker's possessions take up almost no space. That tidy, practical detail carries a quiet sadness, because the things that once filled a room have become invisible.
The mood is reflective and a little wistful, with a plain, matter-of-fact tone. The last lines turn the poem toward a bigger worry: if everything comes and goes, including us, what will we have done with our time? The question is left hanging, and that open ending is what stays with the reader.
