Never do a favour for a frnd unless u get something in return

This summer hasnt been the best for me. It was full of disappointments, one after the other. Yes i have accomplished some stuff but it wasnt enough to over weigh the cons. It has been a shitty 4 months and uni is around the corner and only God knows wut im in for this year. I had work alot for a job interview and showed them that I had wut they needed but for a stupid reasons i was not take and that really ticked my off. So the moment i heard i didnt get the job i hooped on a bus to see my best frnd as he was in another town for only like 2 days. I took the midnite bus to not waste the day. I had no sleep but i traveled another 2 hours by bus to go and see him. I did this for the 2 days which he was there cuz he is after all my best frnd. But now here is where i question somethings, will he remember wut i did for him i did all that spent energy, money and time which i cud have easily toosed or saved away.

Will he do the same for me if the situation presents his self. Since i had alot of disappointments this summer i have started to questions everything. A wiseman once sed, Never do a favour for a frnd unless he is giving u something in return and also try to make sure u get the return b4 u do the favour. I used to be like that guy is screwed in the head cuz thats just something to stupid to say but the truth is that sometimes i actually thinkthat crazy old man was rite. I should start questioning everything. Then this other guy who i thought i can trust and who has come to become a dear frnd has become like all screwed over and i get the feeling that i cant even count on him is something were to happen and i really need some help.
