Ode to a speck

A singular speck So rarely noticed More often removed rather than studied But here you are, you made it In view! All we crave and despise 'to be looked at' I see you now, your fleeting time On the side of the roll top bath I happen to be in You knowing nothing of me I learn very little of you Other than you aren't any type of creature I found that out by gentle squashing An unfortunate way if you were But you are clearly a tiny bit of sand Quite historical if you had a tale to tell The years you have existed Perhaps resided in one place watching it change Or travelled with the tides I've half a mind to return you to a beach But how strange to save a single grain of sand I have some thinking time It will include you and your fate
