Soulmates

How is it possible, that two people who are so different from each other can be so in love with each other.
How is it possible, that two people who were complete strangers a few months back can be so inseparable now.
How is it possible, that no matter how bad your day is, a simple reassuring smile from that person would make you forget everything.
How is it possible, that any problem seems to fade away in their loving embrace and you feel like staying in that embrace for eternity.
Maybe this is what they call as being soulmates.
