There’s probably many pictures of you and your sweetheart together. If you’ve been together long, it may have been a while since you had one with just the two of you.
Time to change that and make it a romantic event.
Find one of those touristy photo places, maybe one doing “old-tyme pictures”. Get dressed up and have some pictures taken.
Afterwards, find a soda fountain or a restaurant with an old time theme. Over dinner, ask your sweetheart, “if we could go back in time 100 years or more, what do you think would be something romantic we could do together?”
Should start a great conversation and create a fun memory. Have fun. Robert
