That sucks!

Well you have 2 options:
1.- Pretend you like it and everything.
2.- Tell him the truth, even though it might hurt him, who knows? he might appreciate it and you might use the gift sometime in the future.

Think about both situations... I advice telling the truth... I know it can be painful but.. he'll appreciate it in time

Good luck!!!

Tell the truth! He'll appreciate your honesty.

Yeah... but she's more mature than him, she will appreciate the truth too. She should...

It'll be a LOT easier in the long run if you just tell them right now, then they can return it and you can go with to pick something out that you really do like

Otherwise you have to deal with slowly wearing it less and less, then him eventually asking, "What happened to that bag I got for you?"

Tell him that this is why he shouldn't spend money on girls at this age.

Or just ask them what they want

Just tell him, at least then he knows not to get you another like it again?

Give the present a chance and learn to love it?

I think his mom chose the present xD
I think the most important is to tell the truth, maybe he gets upset for a while but then he'll get it, or..... tell him some story like: I was walking/in school/shopping and my bag was stole!.. if you dont wanna hurt him

Tell him the truth or lie. Lie that you love it and it temporarily fixes things. problem is he will think you like it and you will be forced to carry it around in public. Also he may buy you accessories that match the bag.Chances are you won't like any thing related to it. Or just tell him the truth and hurt his feelings. But if he was willing to buy you something that expensive, he cares for you. So he will get over it.

You never know, you might grow to like the bag, but always go with the truth. Honesty never fails you in a relationship, because if it doesn't work out, then it wasn't meant to be.

Most boys are clueless about bags, so if he chose one that doesn't suit you, its a not a reflection on how well he knows you, its a reflection of how aware he is of female fashion. Or maybe of how aware his mum is of teenage girl fashion. Either way, he clearly wanted to buy you a nice present, & that should mean more than the bag.
Telling his mum & him that you don't like it would imo be counterproductive. They aren't going to go buy you a new one, so the only thing that would accomplish is making them both feel bad and you feel awkward. Use the bag once in awhile right now so that he can feel good about it, and within a couple months he'll forget it exists so you can just stick under you bed & forget about it too.

Tell him the truth about the present

Tell him the truth about your appreciation for his gesture

Truth be told.

If you do not like it, tell him so that he can return the bag. Yes his feelings will be hurt, Yes they will get a little bit impatient with you. Also, do you not like the bag because you are very picky and do not have open mind? Or is it another reason.

his mother paid half for it?, I'd say keep it and play it safe
