Promising to give something to someone
Q:
1. If I told someone that I will give you this dress, that person didn't say anything, can I change my decision and keep the dress for myself?
2. I told a person that I will give you something but that person said he does not need it, but I insisted on him to accept the offer and he somehow agreed, then later I thought in my mind that maybe that person really don't need my thing so well I will give it to some other person then, so can I change my decision like this?
