You get wise or warts

I poked around in the garden for an hour when I came back from walking. Somewhere between the strawberry and lettuce beds, I met a little friend. He had a British accent and a slightly uppity air but I liked him right away. He had been paused in the search for his misplaced top hat by my mumbled talking to myself and when I paused he looked up and said kindly, Do be careful, my dear, the gardens have ears. He made a move to go before adding, and I say, it's hardly a cakewalk being a toad either, you know, and he hopped on.
