Is this a quote that someone who's single would share or someone who is in a relationship currently but is unhappy?
Either, or someone who doesn't care how immature he or she looks. When you're in a relationship with someone you care about, you understand there are days when you need to accommodate the wishes or needs of others, even when you don't feel like it. Mature people realize that a relationship isn't like Little League, where everyone wins every day and nobody has to do anything they don't want to do. Adults do stuff they don't want to do every day, without b----ing about it.
could be either .. someone thats been in a bad one before i would guess ..
