It's better to have a circle of friends, maybe 1 or 2 really close ones whom you can really pour out your heart to. Nowadays people move onto to other jobs, cities, countries, so it's better to have different friends for different things that you enjoy[ eg shopping, movies, holidays]. One person cannot possibly fulfil all your needs, they'd have to be superhuman.

I think you're stuck on the difference between the literal meaning and the figurative meaning of "give heart and soul". If we understand them literally, and if we only have one heart and soul, then, yes, we can only give them once. (Also, it would kill us to do so!) However, "give your heart to someone" and "give your soul to someone" can - and almost always are - understood metaphorically, with a meaning similar to "devote your heart/soul to someone", whence it is possible to "give" heart or soul to more than one person - assuming it is possible to devote something to more than one person or thing. The problem, as you frame it, is not a logical problem, it is a semantic problem.

your heart and soul is kinda spread out for all of your closest friends. well, that's my view anyways. ^^ --asia

yes u can give or do anything if u have a truth friend

in my opinion I beleived in that there is no faithful friend in this world accept the mother. it is the most faithful in this word . it is impossible from the mother to hurt her sons ,in the contrary she is always service the till her death, and I think there is no one can service the other till his death accept the mother. other wise we must have friends in our life ,the friend ship is very beautiful realation .
