23. What do you think of best friends of the opposite sex?
A contentious issue. It rather depends on the people involved. Personally, I have had close male friends, but it ended up a bit awkward as at least one of them wanted to develop it further. It also becomes a tad difficult if you are married to someone and you try to maintain a close friendship with said close friend. Sex and jealousy always raises its ugly head, unless there are different parameters within that friendship, like your opposite sex bestie is a blood relation, or gay etc. The complexities arise if there are unresolved/unrequited feelings.
I know that it is quite normal to have a platonic friendship with your opposite sex bestie and I am sure that there are many examples of this - but in my personal experience, if you have this, you are very lucky. Feel blessed :-)
