Alone vs with friends

Alone vs. with friends
If asked if one prefers to spend his time alone or with other people,
in reality, for most of people it is impossible to answer give an
answer as black or white, because one needs the both though the
way of how to balance between the two should be different
depending on individual. However, I would say that recently I put
more preference to spending my time alone than to spend with
friends for the following reasons.
First, these days I am more interested in improving myself as
professional than sharing funs with my friends, and so I like
spending my free time reading and studying alone. I would like to
take advantage of being single because I know that after the
marriage, especially after giving a birth to a baby, it is very
difficult for a woman to find time to study for her own.
Secondly, now I do not have many friends with whom I can go out
in my free time. When I was younger, I used to like going out with
my friends and also I had more friends to study together. But now
most of my friends are busy with their family matters or work and so
they are also not interested in having funs with friends nor have time
to study together. Now my communication with them is mostly by
emails and telephone, instead of sharing our free time together.
Thirdly, I have very good relationship established with my
coworkers at work, which certainly satisfies my emotional necessity
of sharing things and feelings with somebody. We eat lunch
together every day, joking and talking about our personal issues.
Therefore I do not feel lonely even when I do not have any
invitation and spend the weekend at home alone.
In conclusion, thus, my preference about how I spend my free time
has changed very much since when I was younger and for me now
the time I spend alone is more important
to improve my ability.
