Flotsam and Jetsam

Today as I walked on the beach it seemed to speak to me - reflecting my life as it is just now

From the safety of the grassy bank
to large rocks - all tumbled together, no firm footing anywhere, but still beauty there

and then to larger rocks, firm, embedded and steady offering resilience and sanctity

and then more rocks, decreasing in size until they are just pebbles disappearing under my feet and pushing together provide thier own stability

Finally reaching the sand - sometimes obstructed by large clumps of weed; or the flotsam and jetsam that has washed up and will be washed again on the next high tide; if it is dry it takes effort to walk on it, when wet, it offers a firmer footing - but even if it looks firm, until you step onto it, you do not know... you need to take that step!!

Over the past two weeks, i have contacted numerous vacant charges from The List, only to discover that 6 had already found someone; 1 had problems and was not taking applications, 1 was just too big... another just wrong... 5 I have visited which put 4 of those out!!
I have 2 left one I've visited properly, the other is so far away I'll have to plan an overnight

Where am I?
Rocks?
Pebbles?
Sand?
Hiding in the driftwood?
