I hate my mind at times

So guys I wanted an ice cream from the ice cream truck and sprinkles ! For awhile I never had money on me to get it and always felt bad because I would want one and to share with my one year old son, today I finally had money but my son wasn’t with me and I felt so sad if I was to buy one and he wasn’t here with me to share with me . Mind you iv been craving it so since I couldn’t find the change I just told the guy nevermind and I walked away kinda wanting it lol but since I’m also watching what I spend I thought if I see it next time with my baby I’ll keep the three dollars and 50 cent so next time I’ll get it for us .
