पाठ में ऐसे कई प्रसंग आए हैं जिन्होंने मेरे दिल को छू लिए-
(1) रामायण पाठ कर रहे अपने पिता के पास बैठा हुआ भोलानाथ का आईने में अपने को देखकर खुश होना और जब उसके पिताजी उसे देखते हैं तो लजाकर उसका आईना रख देने की अदा बड़ी प्यारी लगती है।
(2) बच्चों द्वारा बारात का स्वांग रचते हुए समधी का बकरे पर सवार होना। दुल्हन को लिवा लाना व पिता द्वारा दुल्हन का घूँघट उठाने ने पर सब बच्चों का भाग जाना, बच्चों के खेल में समाज के प्रति उनका रूझान झलकता है तो दूसरी और उनकी नाटकीयता, स्वांग उनका बचपना।
(3) बच्चे का अपने पिता के साथ कुश्ती लड़ना। शिथिल होकर बच्चे के बल को बढ़ावा देना और पछाड़ खा कर गिर जाना।

In a system of flexible exchange rate, the exchange rate of a currency (like price of a commodity) is freely determined by forces of demand and supply of foreign exchange in the foreign exchange market. Expressed graphically, the intersection of demand and the supply curves determines the equilibrium exchange rate and equilibrium quantity of foreign currency.
