Learning to be me

I wanted to know how could someone say that they're your friend however, when u r unable to do for yourself they are not there to fill in the gap...meaning if its just a phone call to say "Hey, How are you doing"...or something...I just can't understand that at all...However, when you are going thru whatever you are going thru ....that shows a person character and true friendship...so just be carefully who you consider a friend and  associate.....time bring on changes and some are good and some or bad....just be prepared to expect the unexpected......people are not who they appear to be.....
